Rand PaulRandal (Rand) Howard PaulWatchdog calls for probe into Gohmert 'disregarding public health guidance' on COVID-19 Massie plans to donate plasma after testing positive for COVID-19 antibodies After trillions in tax cuts for the rich, Republicans refuse to help struggling Americans 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 SchumerChuck SchumerIn the next relief package Congress must fund universal COVID testing Ocasio-Cortez's 2nd grade teacher tells her 'you've got this' ahead of DNC speech New poll shows Markey with wide lead over Kennedy in Massachusetts MORE's (D-N.Y.) request that former national security adviser John BoltonJohn BoltonThe Hill's 12:30 Report - Speculation over Biden's running mate announcement Ex-Trump adviser, impeachment witness Fiona Hill gets book deal Hannity's first book in 10 years debuts at No. 1 on Amazon 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.

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.
