Sen. Kennedy: Trial Could Last to 'April or May' With Witnesses

Calling new witnesses during the Senate impeachment trial of President Donald Trump would extend the proceedings "through April or May," according to Sen. John Kennedy, R-La.

"If we make the decision to hear from more witnesses and to grant the subpoenas that our Democratic friends are asking for, I think we will be here through April or May," Kennedy told Fox News' "The Story" with Martha MacCallum.

Democrats have long lobbied for the Senate to subpoena new witnesses after the House impeachment inquiry did not call for testimony from the likes of then-National Security Adviser John Bolton or White House chief of staff Mick Mulvaney – both of which would have first-hand interactions with Trump with regard to the request for Ukraine corruption investigations.

Bolton has said he would testify, but Trump has also said he might invoke executive privilege against it.

This weekend, an excerpt from Bolton's upcoming book suggests Bolton was told Ukraine aid was delayed until Ukraine vowed an investigation of Joe Biden, his son, Hunter, and energy company Burisma. Trump has denied that, saying he "never" told Bolton anything like that.

That news has increased the calls for Bolton's testimony before the Senate, but Kennedy said that is not true of the GOP members in the Senate jury.

"I've seen the articles that you might be referencing [indicating that] there's been a change in momentum," Kennedy told MacCallum. "I don't sense that. I still think that, based on what I've seen so far, the vast majority of my colleagues, not my Democratic colleagues but Republicans, have decided that we have heard enough."
