Chicago tribune says today, bring on game seven. The headline on the Cleveland Plain Dealer says it all, buckle up. This is the cbs eveningis this is the cbs evening news with scott pelley. This is the cbs evening news pelley shameful acts of violence, that is what president obama called the ambush murderst of two iowa Police Officers. Sergeant Anthony Beminio of the Des Moines Police department and officer Justin Martin of the urbandale p. D. Were assassinated last night without provocation in separate shootings. Tonight a suspect is under arrest and David Begnaud is in des moines. Reporter it was just after 7 00 a. M. Officers found rookie officer Justin Martin shot dead in his patrol car. More than 15 rounds were fired s about three minutes later andp less than two miles away, Des Moines Police sergeant Anthony Beminio was shot at a stop sign. He died at a local hospital. Des Moines Police spokesman paul parizek. They were ambushed. Its nothing less than a slaughter. These officers had no idea what was to come. At reporter by 9 25 a. M. Police had 46yearold Scott Michael greene in custody. Greene had flagged down a state employee, showed him his i. D. And asked him to call 911. He was arrested without incident and taken to a hospital after saying he felt sick. K. Police believe greus rifle to execute the lawmen. I think he had full awareness of what he was doing when he killed those officers. The way that this happened isnt something that seems spur of the moment. Reporter greene has a history of harassment. Just two weeks ago he waved a Confederate Flag at a High School Football game. This video shot by greene shows police asking him to leave. Have i committed a crime . Youre on private property. Youre on school property. Were asking you to leave at this time. Reporter Justin Martin was just 24 years old. He had only been on the 39yearold Anthony Beminio, a father of three, had been promoted to sergeant after more than ten years at the Des Moines Police department. We dont think these officers were specifically targeted because they were Justin Martin and tony beminio. This is the only thing they know, how to help. Reporter at the crime scenea in urbandale this morning, there was a moment of gratitude for the police. And i want you to go home to your families because i want my dad to come home to me and i want my friends to come home to me. Reporter the suspect has nor yet been charged criminally and a motive is unknown. Authorities say its entirely possible the gunman didnt really know the two officers hee ambushed, but he was wellknown to Law Enforcement in this area through previous runins. Viou scott, one officer told us a short time ago, this guy has been a thorn in our side for a long time. S pelley David Begnaud in iowa. David, thank you. Hillary clinton tweeted that sh. Is heartbroken for the families of the officers, and donald trump tweeted today that they the long president ial campaign is finally down to six days. We have two reports on the strategies for the homestretch, and first well go to nancy cordes covering clinton. Reporter to win in florida, clinton needs to generate obama level enthusiasm, especially from African Americans, who made up a quarter of the states early voting electorate when he was on the ballot in 2012. So far this year that rate is off by about seven points. Reporter today the president and clinton made the rounds again on predominantly black radio stations. Reporter in battleground north carolina, African American early voting rates are bouncing back from a slow start after republicans there imposed strict limits on the number of urban polling places during first week folks were beaten trying to register voters. Reporter in chapel hill today, mr. Obama issued this dire new warning about a trump presidency. I hate to put a little pressure on you, but the fate of the republic rests on your shoulders. Reporter the latino vote will also be key for clinton, and there the numbers are far better. In florida, hispanic early voting is up 139 from this point in 2012, driven in part by trumps comments about mexicans. I mean, he starts out by he moves on to insult all latinos, insults African American, insults muslim, insults people with disabilities. Reporter president obama came to clintons aid on another front today, criticizing the f. B. I. Director for alerting congress about new emails in the clinton case that may or may not be significant. The president said the f. B. I. Information. Nd scott . Pelley nancy cordes on the campaign trail for us tonight. Now lets go to Major Garrett, who is covering the Trump Campaign. Get out there and vote. Pretend were slightly behind. You got to get out. We dont want to blow this. Reporter donald trump is running like an underdog even as new polls show the race in florida is essentially tied. For a second day, he warned that a Hillary Clinton presidency could be mired in congressional and possibly criminal investigations. Elected, it would create an unprecedented and protracted constitutional crisis. Havent we just been through a lot with the clintons . Right . C reporter despite the public polling, trumps team believes it has surged ahead here. It also believes it has drawn even in upper midwest states like michigan and wisconsin. In eau claire last night, trump made a play for voters who cast clinton and are now suffering what he called buyers remorse. A lot of stuff has come out since your vote. Reporter at least four states allow early voters to withdraw their ballots and re vote, but state Officials Say the practice is rarely used. Still, trumps pitch speaks to the campaigns buoyancy in the final week. It was also visible in the roughly 600,000 dollar investment in three trumpmp commercials slated to air nationally during tonights game seven of the world series. Everyday people stand united, broken politics with a new leader who is not a part of the system. Reporter trump continues toc raise money, 2 million this morning in miami from wealthy republican donors, a whoppingor 100 million in the month of october through small dollar donations. Scott, were told the Republican National committee and the Trump Campaign have fully funded their Field Operations and every trump tv commercials. Pelley Major Garrett for us. Major, thank you. Major, nancy, and our entire campaign 2016 team will bring you live Election Night coverage next tuesday at 7 00 eastern time. Tonight, we are listening to millennial voters, many of theml voting for the first time. F clinton has a 28point lead among them in a poll by harvards institute of politics. More than half say they are fearful about the future. Elaine quijano gathered a group ages 18 to 34 from 12 stat. They met at the Youtube Space in new york city for our campaign 2016 series closing arguments. Im a very proud conservative, but i dont think that donald trump represents the republican party. Im 20 years old. Im an unapologetic american and fullblown trump supporter. Im 19. Ill vote for gary johnson. Im 27 and im with her. Im not with her and i dont support Hillary Clinton. I say im a trump supporter. Homophobic and xenophobic. We automatically jump to conclusions a trump supporter is a bad, uneducated supporter. He says a lot of stuff i 100 do not agree with, but at the same time, i dont want to support a liar. Reporter how many of you here have had college debt or you will soon have college debt, student debt . By the time im finished with my education, im going to have over 200,000 in debt. In order to get a bett youre forced into higher education, forced into this debt. I dont think really either candidate has posed a good enough stance. Reporter i want to turn to another topic here and that is the issue of civil rights. A recent poll found that 85 of young African Americans and 72 of hispanics believe their race is under attack in the u. S. I wonder why do you think that is . Something thats really dear to my heart because i was robbed and shot in my head. If that wasnt enough, i look up and i was staring down the barrel of another gun. This time it wasnt the barrel of a gun from someone else trying to rob me, this time i was looking down the barrel of the police. Reporter let me ask you, youre the son of a former police officer, is that right . He actually recently retired. I think there are bad Police Officers. Corrupt Police Officers, but i think obama has not done a decent job at helping the African American community, and i think Hillary Clinton is part of that. But i do support our police. On the comment about Police Officers versus the black lives matter, the African American community, you have a choice to be a cop. You sign that. You go to training for that. You have no choice being black. And trump has normalized this talk and put a lot of lives in danger. Hasnt been in the white house, so to say that trump tore our country apart at the seams and created this racial division, in way. President obama was the one who is in the white house for eight years, and Race Relations have been worse than ever in this country. Lets look at who is in office. An African American man who has torn apart this country. We need the look at that. To say that Race Relations have gotten as bad as theyve ever been under president obama shows a lack of historical depth. America is built on racial division, and Donald Trumps rhetoric, this otherism, plays on that narrative that has long been the narrative of american society. Reporter while there were passionate disagreements, one issue united this group, debt. Many told me they cant repay their student loans, which means theyre putting off decisions like buying a house or starting a family, and, scott, theyre looking for answers from these candidates. Pelley Elaine Quijano listening to the voters tonight. Elaine, thank you. Fascinating conversation with millennial voters on our cbs News Youtube Channel and on our streaming service, cbsn. Police are investigating a fire last night at a predominantlyer African American church inlle, greenville, mississippi, last night. Someone spray painted vote trump on the Hopewell Baptist church. Vo there are no suspects, but the mayor is calling it a hate crime. Al a complaint has been filed with the federal election comss alleging that a Boston Law Firm broke Campaign Finance laws with fraudulent donations to politicians, mostly democrats. S. The case was turned up in a joint investigation by the boston globe and the center foe responsive politics. Tony dokoupil has details. Reporter the Thornton Law Firm has ten partners, but law dollar for dollar its one of according to the firms own donnels leaked by a whistleblower days or hours after making these donation, parties received money matching the amount they gave. F once the law firm knew we had these records, they didnt deny that this was the case. Nd reporter scott allen is the globes spotlight editor. So hundreds and hundreds ofel times a lawyer would donate money to a candidate or c political party, and then almost immediately be given back that very same sum. Thats correct. Nd reporter if you give a donation and then somebody elsee reimburses you for the donation thats a clear violation of the spirit and the letr reporter federal law limits partnerships like the Thornton Law Firm to a maximum donation of 2,700 per candidate. Thornton is alleged to have made donations above that limit by using a straw donor system, using the firms own money, but making it appear it was from individual partners. Rs viveca novak is with the center for responsive politics. Straw donor reimbursement systems are something that both the f. E. C. And the department of justice take very seriously. And people have gone to jail for this. Reporter but the spotlight three of the firms partners from 2010 to 2014. The trio donated 1. 6 million, mostly to democrats. Over the same period, they received back 1. 4 million in bonuses. A thornton spokesperson said the donations were legal because they came out of each partners ownership stake in the firm. It was a voluntary program,o thornton stated, involving the e partners own personal aftertax money. Thornton donated to dozens of democrats, including some of the most hotly contested senate races. Some of those democrats,e including Hillary Clinton, said theyd be returning donations, but, scott, thornton told us it hired an outside firm to review its political donations and thai it has complied with election law.

Reporter its the lesser of two evils. Thats where were at. Reporter lawmakers blame a since 2014. Is y this year the state faced a 1. 3 billion deficit and cut 34fi million in education funding.
