What we can learn from her experience. And, we follow the children of 9 11 heroes as they follow in their parents footsteps. This is the cbs evening news with norah odonnell. Brennan good evening. This is our western edition. Norah is on assignment. Im margaret brennan. The impeachment process is on. President trump and House Democrats are now on a collision course. House Speaker Nancy Pelosi late today announced plans to move ahead with an official impeachment inquiry. She had been reluctant to do that, but changed her mind after at least 170 House Democrats came out in support of it. That follows reports that the president tried to pressure ukraines leader to open a corruption investigation of joe biden. Pelosi calls that election interference. Also tonight, the governmentwhth tleb tisr insewe committee. And the president , who says he has nothing to hide, says he will release a transcript of his phone call with the ukrainian leader. We have a team working on this on capitol hill, the white house, and the u. N. Well begin with nancy cordes on capitol hill. Im announcing the house of representatives is 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. Well, 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 . I 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 give know an explanation. Fortunately, it finally happened, and im glad about that. Brennan nancy, extraordinary comments there from republican leadership. What happens next . Reporter well, the house and Senate Intelligence committees are now 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. And, margaret, its very significant that the republican led senate is now looking into this, along with the democrat led house. Brennan nancy cordes, thank you. Well, the president wasted no time reacting to this. He is here in new york for the United Nations general assembly. Weijia jiang is here. Look, its just a continuation 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 . President ial harassment. Earlier in the day, he tweeted he will release tomorrow a complete, fully declassified 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 denies he pressured ukrainian president Volodymyr Zelensky in that july 25 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 the only one paying to ukraine . Reporter mr. Trump claims thenvice 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 the 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, margaret, that call is just one piece of evidence the democrats want to review. Brennan weijia jiang at the United Nations. And those two leaders will meet tomorrow here in new york. Major garrett joins us now from our washington, d. C. Bureau. Major, what are you hearing, and what are you learning tonight in your reporting about the administrations response . How are they going to handle it . Reporter well, theyre going to handle it, margaret, with something approximating glee, anticipating a rallying of the president s base and predicting majorityending jeopardy for House Democrats. Thats now the current mindset. With it will come fights to block subpoenas and witness testimonies, 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 Senate Democrats would vote to impeach. Brennan and only two u. S. President s have ever been impeached before. This doesnt necessarily remove the president from office. But what impact does the fight itself have on the country . Reporter well, i covered the clinton impeachment, and impeachments cast a long shadow. My experience, they deepen partisan division. Lets look at richard nixon, first. The house didnt even vote on articles of impeachment, but he resigned anyway, leaving a raft of reformist laws and liz trust in government in its wake. The house did impeach bill clinton, but he survived the senate trial. But clintons presidency lost energy, 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. Brennan Major Garrett in washington, thank you. In another big story tonight, disturbing scenes of a man dying inside his own apartment were played today at the murder trial of a former Dallas Police officer. Amber guyger says she mistakenly thought the unarmed victim, botham jean, was in her apartment. Omar villafranca shows us what police found at the scene, and we warn you, it may be hard to watch. Reporter the bodycam video shows officers sprinting up the where their fellow officer, amber guyger, had just shot botham jean in his own apartment.

Come on, jean reporter for over seven minutes, officers took turns applying chest compressions as the 26yearold laid on his back bleeding from a fatal gunshot wound. Dallas Police Officer michael lee once you and officer blair began the regimen of providing him aid, did you and your fellow officers stop for any reason . No, sir. Reporter the prosecution believes the shooting occurred in part because guyger was distracted. Earlier, they showed evidence that she was talking and sending sexually explicit texts to her patrol partner, officer martin rivera, who she had a romantic relationship with. The jury also heard guygers 911 call. Reporter the former officer could be seen wiping her face as it played. The jury saw a video that showed guyger she did not walk in jeans door. In fact, his door was slightly open. And, the defense is arguing, not only did she think that was her door, but she thought someone was inside. Margaret.

Still, Jennifer Shelton said her husband was afraid he would lose his job if he revealed his illness.

Reporter harper was rushed to the hospital, her third trip to a dallasarea medical facility in two days. They charged me for blood typing.

The amount she was charged for the same tests, a pair of ultrasounds, at two different facilities 150 at her birthing center, but more than 1,500 at this hospital. Are you surprised by that .
