Five weeks later, the power is still out in most of puerto rico, and now lightbulbs are going off in the heads of members of congress. Theyre calling for an investigation of the deal that awarded a big contract to a tiny company to get the power back on. The company happens to be headquartered in the hometown of a member of the trump cabinet. Julianna goldman is looking into this. Reporter its been more than a month since Hurricane Maria ravaged puerto rico, leaving its power grid in shambles. Today 75 of the island is still without power, and lawmakers in both parties are asking why a Small Montana company was granted a 300 million nobid contract to help rebuild transmission and distribution lines. My biggest concern is we dont have enough information as to the process that went through that. Reporter republican congressman rob bishop chairs the House Committee that oversees puerto rico. The Government Power Company known as prepa signed the contract with whitefish energy, a twoperson, twoyearold Company Whose largest previous federal contract had been for 1. 3 million to upgrade lines in arizona. Prepa filed for bankruptcy in july amid the islands ongoing debt crisis. It bypassed a network of utilities and a mutual aid system that is usually activated for storm recovery. The 300 Million Contract is the biggest yet for puerto ricos recovery effort, and for whitefish, which relies on subcontractors for their work. This appears to be a pretty small company. Are they capable of doing the job that they have . Reporter republican senator Lisa Murkowski chaired the energy committee. She expects a hearing on puerto rico in the next week.

Rnight puerto ricos governor says that hes going to be reviewing the contracting process. Anthony . Mason julianna goldman. Thanks, julianna. Hurricane maria also disrupted production at puerto rican factories that make critical drugs and medical supplies. Dr. Jon lapook found hospitals on the u. S. Mainland are already seeing shortages. This is slated to go to a patient for infusion. Reporter these small bags of intravenous fluid deliver lifesaving medications like antibiotics and chemotherapy. Regine villains job at nyu health is to manage supply, and shes worried. The bags are in short supply. We have been practically handtomouth counting by the thops how much we have in house. Its just really nerveracking to think about not being able to have those bags available for the patients. Reporter her concern is pihoed by hospitals and pharmacists around the country. Ae American Hospital association told cbs news the shortage is quickly becoming a crisis and threat to public health. There was already an existing xiortage for several years, made worse by facilities being damaged by the hurricanes. On top of that, villain says the three major manufacturers usually shut down for aaintenance before the end of the year. This is a thing that keeps me up at night, because i feel that if those shutdowns go on as planned, we could be experiencing unprecedented issues around i. V. Solutions. Ea reporter meaning what . Meaning that we may be in a situation where we have run out of a lot of those necessary i. V. Fluids for the hospital. Reporter salt water, sugar solutions. Thats correct. Reporter thats meat and potatoes stuff. Nd first thing that we do, we hang an i. V. , and thats how we start taking care of you. Reporter weve been told that patient care has not been compromised so far, but its unclear how long that can last given the strain on the system. Anthony . Mason dr. Jon lapook. Thank you, jon. As president , donald trump is also head of the republican party, and he denied today that it is party divided, despite evidence to the contrary, including prominent republicans yesterday calling him an habitual liar and a danger to crmocracy.

Colleagues refused to open fire i mr. Trump. Im still on very good terms with the president. Hes very focused on getting results. Our job is to put our head down and start legislating. Reporter theyre holding back partly because the Trump White House is key to their agenda on issues like tax reform. Ax we now have a president that will sign it. The yeas are 50. The nays are 50. Reporter just last night jce president pence cast a tie aseaking vote enabling republicans to block an obama era rule that would have allowed consumers to band together to sue banks for wrongdoing. The Vice President votes in fhe affirmative, and the joint resolution is passed. We have great unity. Reporter the president atsisted today that Party Friction has been overblown. Nt repeatedly mentioned the oanding ovations he got at yesterdays lunch with Senate Republicans. I think the press makes me knre uncivil than i am. You know, people dont understand. I went to an ivy league college. I was a nice student. I did very well. Im a very intelligent person. Reporter as for flake. His poll numbers are terrible. Hes done terribly for the great people of arizona, a state that erkes donald trump very much. Almighty god. Reporter but the senate chaplain, barry black, hailed flakes courage and asked for some divine intervention. Lord, provide us with more patriots who will stand for right regardless of the consequences. Reporter flakes decision to retire was hailed as a victory by president ial allies like steve bannon, but Senate Republicans argue that is shortsighted. They worry, anthony, that his seat could now get scooped up by a democrat. Mason nancy cordes at the capitol. Thanks, nancy. With the republican president under attack by both of arizonas republican senators, we talked to Republican Voters in the state. Heres jim axelrod. I will not be complicit or silent.

The bigger thing i see is he is fighting for unity. Hes asking us to unite. Po reporter frank tesnati. I think he walked away from a fight he shouldnt have walked fiay from. Reporter and manny ciprot would have liked flake to hang tough. I was disappointed he threw la the towel. Its somewhat premature. Reporter but all four want the namecalling to stop, and all said their patience is ,tarting to wear thin with the weesident, not his policies, his demeanor. I personally agree that the president is more divisive than t is uniting. We vote for these people, we wve them our proxy to represent us, and when President Trump attacks these people personally, hes attacking all of us. Reporter all four of these blpublican voters say they are now a bit more concerned about the 2018 senate race here, as rell. As unpopular as flake is, his departure opens the door to a possibility of a candidate that could have a tougher time holding on to a senate seat that has been in republican hands for two decades. Mason jim axelrod in oroenix. Thank you, jim. President trump told reporters today he did not specifically order the military mission in niger in which four american soldiers were killed. He said his generals made the decision. Weve also learned the pentagon deployed elite commandos to search for one of the soldiers. Margaret brennan is following this. S reporter sources describe lve ambush as a complex attack involving rocketpropelled grenades and smallarms fire. Etvestigators are still trying to determine how or when sergeant ladavid johnson, an army mechanic, got separated from the 11 other u. S. Troops. Uns also unknown whether he was alive when the wounded troops were evacuated. His body was recovered two days later. On the morning of october 4th, the soldiers were on a joint patrol with 30 nigerian earces near the village of tongo tongo where they had just met with elders and loaded up with supplies. They were at the end of a 24hour mission when the attack began, an hour into the fight, the patrol called for help, and French Forces arrived 30 minutes later. The military soon declared a dust one or duty status whereabouts unknown for sergeant johnson. A request was made the chairman of the joint chiefs, joseph dunford, for more u. S. Personnel. U. S. Commandos based in the sgion were launched. At that point, knowing that we had a missing soldier, we made a decision to make sure that all of the resources including National Assets were available for the recovery of that operation. Reporter it is still unclear eaether the attack was pre planned, but investigators nelieve it was carried out by an isis offshoot operating in the area. Ilcording to military officials, the group is run by this man, adnan abu alsahrawi. He commands just 40 to 60 fighters but has allies throughout the region. Alsahrawi is wanted by u. S. And french authorities, but u. S. Intelligence has not established a direct link between him and the isis militants that the u. S. Is already fighting on the battleground in iraq and syria. Anthony . Mason Margaret Brennan at the pentagon tonight. Thanks. President trump today called it a disgrace that democrats helped pay for some of the information in a dossier of allegations against him.

T esident trump continued to dismiss the document today. A it was made up, and i understand they paid a tremendous amount of money. And Hillary Clinton always denied it. Ore democrats always denied it. Reporter the law firm that represented both the Democratic National committee and the hillary for America Campaign has confirmed that it paid fusion gps in april of 2016 to perform a variety of research services. Until now, some top Clinton Campaign officials have denied knowing who was behind the effort to dig up dirt. Former Campaign Spokesman brian fallon. Im sure a small group of folks were aware of the decision the hire fusion back in the spring of 2016. But it was kept for reasons i understand to a very select group, given the sensitive nature of who they hired. Reporter fusion gps hired christopher steele, a former british spy who compiled the dossier containing unsubstantiated information, including President Trumps slleged connections to the kremlin. Alex conant, now a cbs news consultant and worked for marco rubios president ial campaign. Every competent campaign does research on their opponent. You want to know your opponents liabilities. I think hiring foreign spies is r rather aggressive tactic, and thats not normal, but it is normal to do opposition research. Reporter republicans paid fusion gps to initiate the research during the primary. Later as the f. B. I. Found some of the information credible, it considered hiring steele, but when his role became public, that deal collapsed. Anthony . Mason jeff pegues, thanks.
