council's office didn't act more quickly on this whistle-blower complaint. we know that the president has made not-so-veiled threats, but he's not going to be able to ultimately stop an impeachment inquiry from going full steam ahead. >> jeffrey, we know he can't officially stop it. what are the tools he has to try and slow walk it? what do you expect this president do? he's been on a twitter tirade today, a unique one even for him, tweeting multiple times about the investigation, about adam schiff, about the democrats, about the media. he's doing what he normally does when faced with harsh criticism or real questions about abuse of power by trying to point the ficker everywhere else. >> so there aren't a lot of easy constitution an questions but this is one of them. the constitution gives the house and senate sole power to impeach and try impeachments.
