Dems warn against calling Bidens to testify: It "would be literally rolling a grenade down" the Senate

“Look, Joe Biden is well known, widely respected, and frankly beloved by many in the Senate on both sides of the aisle,” said Coons. “The impeachment process is already disruptive enough. I think we should be approaching it with seriousness, not by entertaining conspiracy theories that are utterly unfounded. And I think it would be a very unfortunate move.”…

And even many rank-and-file members have been skeptical of the idea of hauling in the Bidens, saying that they need to keep distance from such matters as potential jurors in the case of a potential impeachment trial. Sen. Ron Johnson (R-WI), who chairs the Senate’s panel on oversight and could call certain witnesses if he wanted, said he’d be interested in hearing from the Bidens “at some point in time” but indicated he was not interested in “show trials.” The senator, who has found himself as a side player in the Trump-Ukraine saga, has frequently referenced reporting from John Solomon, the conservative reporter whose work, while criticized on the merits, has fueled allegations of corruption against the Bidens.

“I’m just trying to tenaciously gather information so we can, at some point in time, determine the truth,” Johnson told reporters on Wednesday.
