Reporter the black river spilled across pocahontas, arkansas, after heavy rains breeched a levee. About 50 homes have been destroyed and up to 100 homes and businesses damaged. Where were the breaches . They were east of here. Reporter Cecil Tackett is the citys police chief. This morning at 6 00 there was fish swimming across here. Reporter across this highway . Yes. Reporter murky floodwaters turned this playground into a water park. Days of torrential rainfall caused a number of rivers near pocahontas to swell as much as nine inches. Add the nearly eight inches that fell in pocahontas la and it was more than the levee could take. The threat of a breech forced a mandatory evacuation of the city of 7,000 on monday. Rising waters sent folks like jeff junkersfeld to move his mom out of harms way. Its sad. A lot of people had to get their stuff out and get out of their element, find places to stay, find places to live. Reporter portions of major highways across the state are closed as sandbags are piled along flooded roads. William brumit is a volunteer. This is kind of a race here. What theyre predicting is it to go up. It will be really close. So were not taking any chances. Reporter the deluge is part of the most extreme flooding in the region in a century. Hundreds of roads are also closed in neighboring states, including missouri. The area around pocahontas is about as flood as a pool table, so while the river may not be rising anymore, scott, the water here could be aro hours or longer. Pelley and the governor of arkansas has now called out the National Guard to help rescue. Michelle miller on the flood watch tonight. Michelle, thank you. In another big story tonight, f. B. I. Director james comey told the Senate Judiciary committee today that russia is the greatest threat of any nation on earth given their intention and capability. And he said the russians are still interfering with american politics. Comey also talked about his own role in the 2016 election after Hillary Clinton blamed him for her loss. Heres zoila jeff pegues. This is terrible. It makes me mildly nauseous to think that we might have had some impact on the election. Reporter f. B. I. Director james comey defended his Decision Just 11 days before the election to notify congress that agents had found more Hillary Clinton emails. The discovery was made on a computer clinton aide huma disgraced former congressman anthony weiner. Comey said he had no good options. So i stared at speak and conceal. Speak would be really bad. Theres an election in 11 days. Lordy would be really bad. Concealing in my view would be catastrophic. As between really bad and catastrophic, i said to my team, we have to walk in the world of really bad. Reporter agents ultimately determined that abedin forwarded emails containing classified information to her husband, but comey said the bureau could not prove criminal intent and did not recommend charges against abedin, weiner or clinton. Democrat dianne feinstein. You took an enormous gamble. The gamble was that there was something there that would invalidate her candidacy, and there wasnt. Reporter democrats pressed comey on why he publicly discussed the clinton investigation during the campaign but did not reveal that the f. B. I. Was also investigating the and its contacts with russia. Senator patrick leahy. Was it appropriate for you to comment on one investigation repeatedly and not say anything about the other . I think so. Reporter comey said attorney general Loretta Lynch forced his hand when she had an impromptu meeting with former president bill clinton during the investigation. Her meeting with president clinton on that airplane was the kapper for me. I then said, you know what, the department cannot by itself credibly end this. The best chance we have is if i do something i never imagined before, step away from them and tell the american people, look, heres what the f. B. I. Did, heres what we found, heres what we think. Reporter yesterday clinton said comeys decision was partly to blame for her election loss. Scott, that prompted a response from the president on twitter. He called comey the best thing that ever happened to Hillary Clinton in that he gave her a free pass for many bad washington newsroom. Jeff, thank you.

Today federal prosecutors said two White Police Officers will not be charged in the Fatal Shooting of a black man in baton rouge, louisiana. The shooting last summer sparked protests in a number of cities. Heres david begnaud. Reporter amid security concerns, the federal courthouse in baton rouge was barricaded as the longawaited announcement was made by acting u. S. Attorney corey amundson. We simply did not have sufficient evidence to prove beyond a reasonable doubt that either officer violated the federal criminal civil reporter Alton Sterlings died on july 5th at the hands of baton rouge Police OfficersBlaine Salimoni and howie lake ii. A 911 caller reported a black man in a red shirt had pulled a gun on someone. Two officers confronted sterling. He resisted. They tased him and tackled him. Officer salimoni yelled, going for his pocket. Hes got a gun, gun. Then prosecutors say salimoni fired three shots into his chest, and as sterling rolled over, he fired three shots into his back. Prosecutors say eyewitness videos do not clearly show whether sterling was reaching for a load. 38caliber handgun that was pulled out of his front pocket. We were unable to establish beyond a reasonable doubt the precise location of mr. Sterlings hand at which the moment the officer states on the recording that mr. Sterling was going for a gun. Reporter Sharon Weston broome is baton rouges mayor. This decision by the Justice Department to not file charges does not mean the Police Officers acted reporter it also has not discouraged cameron sterling, Alton Sterlings 16yearold son. I cant be angry. Reporter why . My dad wouldnt want me to be angry. He would want me to keep fighting for him. Thats what i will do until the end. Reporter Alton Sterlings death sparked large protests in baton rouge, and that spiraled to Police Killings in baton rouge and dallas. Here there is not a single protester tonight. Scott, louisianas attorney general will now decide whether the two officers in sterlings death should Face Criminal Charges at the state level. Pelley david begnaud, thanks. Today President Trump promised peace in the middle east. A meeting at the white house with Palestinian Leader mahmoud abbas, mr.

To mark his 90th day in office, secretary of state Rex Tillerson spoke to Department Employees for just the second time. Tillerson is planning big changes, doing more with less. Margaret brennan was there. My view of how you translate America First into our Foreign Policy. Reporter secretary tillerson explained to state Department Employees how hi plans to implement President Trumps americafirst policy. If you condition our National Security efforts on someone adopting our values, we probably cant achieve our National Security goals or our National Security interests. Reporter tillerson defended the u. S. Strategy to isolate nucleararmed north korea and said conditions are not yet ripe for a meeting with dictator kim jong un. Well it iso ready to sit down under the right terms. Reporter he explained a plan to rebuild trust with russia by getting president Vladimir Putin to broker a ceasefire in syria. The relationship between our two nations is the lowest its been since the cold war. Reporter but tillerson is tackling these thorny issues without the usual top diplomats. Hes still not appointed policy directors for asia, the mideast or russia. Of the 119 jobs that require senate signoff, only three have been confirmed. President trump has nominated an additional seven. Tillerson also did not explain his plan to eliminate more than 2,000 jobs and potentially cut a quarter of the departments budget. But he began a listening tour that will cost more than 1 million. As you know, weve just kicked off this listening exercise, and i really encourage all of you to please go online and participate in the survey online. This is vital. Reporter tillerson hired an outside contractor to help with the reorganization, and that wondering whether these cuts will help streamline the bureaucracy or, scott, simply gut a building already concerned that power is being concentrated in the hands of officials with far less Foreign Policy experience.

Someone used nooses to hang bananas with racist messages on the washington, d. C. , campus.

This is where it was before i tore it down. Reporter right after spring break at texas a m, freshman Adrienne Rubenstein says she found hate hanging outside the schools main library. She tweeted images of two white power posters. They were advocating for a country white, that no other race, no other ethnicity would be welcome here. Reporter last areas president ial campaign exposed americas economic, social, and racial divisions. Since last novembers election, at least 140 instances of racist posters and flyers have been reported on College Campuses in 33 states. It seems clear that the extremists feel emboldened in this current political climate. Reporter Jonathan Greenblatt is c. E. O. Of the Antidefamation League. Weve seen a change in the rhetoric. Some of our worst impulses have moved from the margins to the mainstream. Reporter greenblatts group has tracked what it calls an unprecedented College Recruitment drive by white nationalists. Groups such as american vanguard, american renaissance, and identity europa. Two groups told us the timing is no coincidence. Weve been riding this wave of Donald Trumps election, abte europa members agreed to speak with us. Tbieter would give his real name. Both agreed about the trump factor. Hes the closest to us that weve ever had in recent memory, although wed like to see him go a lot further. You know most people on a College Campus would see this as racist garbage. I think those slurs like racist, white supremacist, nazi, these are antiwhite slurs. Reporter last november, thenpresident elect trump was accused of energizing hate groups, but he strongly rejected that idea on 60 minutes. If it helps, i will say this, and ill say it right to the camera, stop it. Reporter some College Students have pushed back. Just last week racist notes appeared at st. Olaf college in minnesota. Students protested against hate speech in the weekend and the school is considering adding mandatory classes on race and we hope leaders will step up and speak out when hate rears its head.
