Sen. Rand PaulRandal (Rand) Howard PaulMitch McConnell may win the impeachment and lose the Senate GOP threatens to weaponize impeachment witnesses amid standoff Paul predicts no Republicans will vote to convict Trump MORE (R-Ky.) sent a public warning shot on Monday night, saying that if Republicans support Democrats' impeachment witness requests, then he will force votes during the trial on calling witnesses conservatives want to hear from. 
 
"My colleagues can’t have it both ways. Calling for some, while blocking others," Paul tweeted, referencing a Politico report on a similar private warning he gave his GOP colleagues against supporting Senate Minority Leader Charles SchumerCharles (Chuck) Ellis SchumerTrump administration installs plaque marking finish of 100 miles of border wall Sanders defends vote against USMCA: 'Not a single damn mention' of climate change Schumer votes against USMCA, citing climate implications MORE's (D-N.Y.) request that former national security adviser John BoltonJohn BoltonGOP senator 'open' to impeachment witnesses 'within the scope' of articles Trump Jr.: If 'weaker' Republicans only call for certain witnesses, 'they don't deserve to be in office' House Democrats may call new impeachment witnesses if Senate doesn't MORE testify. 
 
"If we are going to give a platform to witnesses the Dems demand, I look forward to forcing votes to call Hunter Biden and many more!" Paul continued.

Collins has not said if she would support calling witnesses, agreeing, along with the rest of the Senate GOP conference, to delay that decision until after opening arguments and questions from senators.

Mitt RomneyWillard (Mitt) Mitt RomneyThe TRUST Act is a plot to gut Social Security behind closed doors Republicans will pay on Election Day for politicizing Trump's impeachment Bring on the brokered convention MORE (R-Utah) has said that he wants to hear from Bolton during the trial but has not specified how he thinks his testimony should be given. Bolton was one of four witnesses requested by Democrats and said he would testify if subpoenaed. 
 
"I support the Clinton model, which means that we will have opening arguments first. Then we'll have a vote on witnesses, and at that stage I presume I'll be voting in favor of hearing from John Bolton, perhaps among others. That could change," Romney told reporters on Monday. 
 
Democrats would need to peel off four Republican senators to successfully call a witness or compel the administration to hand over Ukraine-related documents.

McConnell told Fox News Radio that opening the door to witnesses would pave the way for a "kind of mutual assured destruction," adding that Republicans would "want the whistleblower. We're going to want Hunter Biden."

"You can see here that this would be a kind of mutual assured destruction episode that would go on for a long time," McConnell said.
