Collins: Bolton allegations 'strengthen the case for witnesses'

"The reports about John Bolton's book strengthen the case for witnesses and have prompted a number of conversations among my colleagues," Collins said in a statement. 

Collins, who is up for reelection in 2020 and viewed as a key swing vote, reiterated that she is "likely" to support calling witnesses as part of the impeachment trial. But she added that she believes the decision should wait until after opening arguments from both sides and senators get the chance to ask questions. 


The Times reported on Sunday night that Bolton claims in his forthcoming memoir that President TrumpDonald John TrumpChasten Buttigieg: 'I've been dealing with the likes of Rush Limbaugh my entire life' Lawmakers paint different pictures of Trump's 'opportunity zone' program We must not turn our heads from the effects of traumatic brain injuries MORE tied Ukraine aid to help with investigations into Democrats, including former Vice President Biden and his son Hunter Biden.

The report has injected a new dose of chaos into the Senate's debate over witnesses only days before the chamber is expected to vote on whether or not to allow additional witnesses and documents. Collins was part of a small group of senators who worked to the language guaranteeing the vote into the rules resolution. 

Democrats will need four Republicans to vote with them to open the door to calling witnesses. After the initial up-or-down vote, both sides are expected to be able to make motions for specific witnesses and the Senate would vote on those requests. 

Collins's statement came shortly after Sen.

“It’s pretty fair to say John Bolton has relevant testimony,” Romney told reporters. "I think it's increasingly likely that other Republicans will join those of us who think we should hear from John Bolton."

Every GOP senator, including Collins, voted against an effort to subpoena Bolton as part of the rules resolution that passed last week.
