From the Broadcast Center here in new york city, im margaret brennan. This is the cbs overnight news. Welcome to the overnight news. Im nikki battiste. Thuned stes congress is about to begin impeachment hearings over President Trumps controversial telephone call with ukraines president. Mr. Trump was withholding 400 million in aid to ukraine when he pressed the countrys leader to open an investigation into the biden family. The president will release the full transcript of that call today, and the whistleblower who first brought the call to light wants to testify before congress. Nancy cordes has the view from capitol hill. Im announcing the house of representatives moving forward with an official impeachment inquiry. Reporter after holding out on impeachment for months, House Speaker nancy pelosi said President Trump had violated his oath of office by calling upon a foreign power to intervene in his election. This is a breach of his constitutional responsibilities. Reporter her change of heart came after a cascade of more than 30 House Democrats announced they are now open to impeachment too. The future of our democracy is at stake. This is the president basically saying yes, i colluded what are you going to do about it . I think we have no other choice. Reporter minnesota democrat dean phillips. This behavior at best is unethical and corrupt. At worst, treasonous. Reporter the turning point was the president s acknowledgment that he pushed his ukrainian counterpart to investigate unfounded claims about a 2020 campaign rival. There was pressure put on with respect to joe biden. What joe biden did for his son, thats something they should be looking at. Reporter cbs news has confirmed mr. Trump unexpectedly told top aides to withhold 400 million in military aid for ukraine days before he spoke by phone with that nations new president. Were going to find out what happened. Reporter the senates republican leader was notably neutral today. What rationale did the administration give you this summer for holding up military aid to ukraine . Talked to the secretary of defense twice, the secretary of state once. I have no idea what precipitated the delay. Reporter they never gave you a reason . I was not given an explanation. Fortunately, it finally happened, and im glad about that. The house and Senate Intelligence committees are both working overtime to try to nail down interviews with the whistleblower who filed a complaint about all of this a month ago. A lawyer for the whistleblower says hes eager to speak to congress after the director of National Intelligence decided not to hand the contents of his complaint over to congress. Its very significant that the Republicanled Senate is now looking into this, along with the democratled house. While all this was going down in washington, President Trump was in new york, addressing the United Nations general assembly, but his call to ukraine is all anyone was talking about. Weijia jiang has the story. Look, its just a continue of the witch hunt. Its the worst witch hunt in political history. Reporter President Trump reacted angrily on twitter after nancy pelosi announced a formal impeachment inquiry, writing, can you believe this . And president ial harassment. Earlier in the day he will release a complete fully unclassified and unredacted transcript of my phone conversation with president zelensky of ukraine. It was a perfect call there was no quid pro quo. Reporter the president denied hi pressured ukrainian president Volodymyr Zelensky in that july 25th call to investigate joe biden and his son or the u. S. Would stop promised aid payments. I could have. I think it would probably, possibly have been okay if i did, but i didnt. Reporter but his explanation for blocking that aid has shifted. Yesterday it was fear of corruption in ukraine. Were supporting a country. We want to make sure that country is honest. Reporter today, burden sharing. Because i think that other countries should be paying also. Why is the United States only one paying to ukraine . Reporter mr. Trump claims then Vice President biden had a ukrainian prosecutor fired to avoid an investigation into his son hunter, who served on the board of a Ukrainian Energy company. But prosecutor was fired because he wasnt investigating corruption, a move supported by several countries. If we allow a president to get away with shredding the United States constitution, that will last forever. Reporter President Trump insists the transcript of his call with the ukrainian president will exonerate him of any wrongdoing. But cbs news has learned that whistleblowers complaint involves multiple allegations. So that call is just one piece of enccratwant to review. Major garrett has a look back at the history of president ial impeachment in the United States. Reporter anticipating a rallying of the president s base and predicting majorityending jeopardy for House Democrats, thats mao the current mindset. With it will come fights to block subpoenas and witness testimony as the white house has since the Mueller Investigation ended. The white house also knows, margaret, that if the house does vote to impeach, a twothirds Senate Majority would be required to convict. Not only is there no sign of, that its unclear if all set of democrats would vote to impeach. Impeachments cast a long shadow. In my opinion that. Deepen partisan convictions. The house didnt even vote on particles of impeachment but he resigned anyways, leaving a raft of reformist laws in its wake. The house did impeach clinton but he did survive the trial. While clinton assets presidency lost legitimacy, al gore was a political casualty in 2000 and nearly two decades of simmering republican anger rose again in 2016 against hillary clinton. Impeachment is the most serious action taken against a president , and no president , and for that matter, no congress emerges unscathed.
