"House Republican leader Kevin McCarthy, a Trump ally who has said he opposes impeachment, has reportedly decided not to ask rank-and-file members of the party to vote against the measure.
According to the New York Times, Senate Republican leader Mitch McConnell has told confidants he is pleased Democrats want to impeach the president because he believes it will help rid the Republican party of Mr Trump.
Mr McConnell has also told associates he believes the president committed impeachable offences, reports the Washington Post.
In the time it took Air Force One to fly Donald Trump back from the Texas border on Tuesday, the political ground crumbled beneath his feet.
And even before the riot at the US Capitol, Mr Trump was increasingly viewed as a political liability with dwindling power. His scorched-earth challenge to the election results probably cost Republicans two Senate seats in Georgia, and there has been scant proof that Mr Trump boosts the party's electoral chances when his name is not on the ballot.
Mr McConnell, among others, may be mulling whether a clean break with Trump is better for their political futures, even if it means working with Democrats to do the job."
I'll believe it when I see it.
