groundwork will be laid for president trump to, it appears, become the third u.s. president ever to be impeached. there's also brand-new cnn polling to show you this morning. it shows the american public divided about impeaching the president. >> and breaking overnight, the president's personal attorney rudy giuliani has admitted to some of the very actions that helped lead to this inevitable impeachment. you might even call it a confession, bragging. in one interview, giuliani said he needed to get the former u.s. ambassador out of the way because she was going to make investigations into the president's rivals difficult for everybody. and then in a new interview overnight, giuliani implicated his boss. he said he briefed president trump a couple of times earlier this year about removing ambassador yovanovitch and the president said basically turn it over to the secretary of state mike pompeo. again, rudy giuliani saying all of this the day before the president is going to be impeached. basically running around saying, yeah, i did it. joining us now, jeffrey toobin,
