We could be looking at just a couple of weeks here.
Senate Republicans are so confident of acquittal that they want to limit the whole show and may not call witnesses. At the very least, they won’t bring in Hunter Biden or the whistleblower, because some Republicans are opposed and they need 51 senators to call a witness.
According to the Washington Examiner:
Senate Republicans do not expect to call witnesses President Trump might want to hear from most in an impeachment trial, conceding there are not the votes to summon key figures such as Hunter Biden and the unidentified government whistleblower whose complaint sparked the process.
Senate impeachment rules require a majority vote to call witnesses, and with just two out of 53 votes to spare, there is no “appetite” among Republicans to pursue testimony from people that Democrats blocked Republicans from subpoenaing during the House investigation. Indeed, Republicans might forgo calling witnesses altogether, saying minds are made up on Trump’s guilt or innocence and that testimony at trial on the Senate floor would draw out the proceedings unnecessarily.
“Here’s what I want to avoid: this thing going on longer than it needs to,” Sen. Lindsey Graham of South Carolina told the Washington Examiner. “I want to end this.”
Top Republicans are leaning toward calling for a vote to acquit Trump immediately after House Democrats and the White House have delivered their arguments to head off partisan disagreements that might lengthen the trial.
“At that point, I would expect that most members would be ready to vote and wouldn’t need more information,” said John Barrasso of Wyoming, the No. 3-ranked Senate Republican. “Many people have their minds pretty well made up.”
That would amount to a slightly extended version of events (two weeks or so) of what some observers had once thought might occur, though was never seriously considered: Republicans holding no trial at all and simply voting to acquit.
