A group of 30 freshman Democrats, led by Rep. Dean Phillips (D-Minn.), has asked House leaders to consider the libertarian, who left the Republican Party earlier this year, for the small group tasked with arguing its case for removing Trump in the upper chamber, according to several Democratic officials.

The thinking, according to these people, is that Amash would reach conservative voters in a way Democrats can’t, potentially bolstering their case to the public. He also would provide Democrats cover from GOP accusations that they’re pursuing a partisan impeachment; Amash is one of the most conservative members of the House and a vocal Trump critic.

“To the extent that this can be bipartisan, it should, and I think including Representative Amash amongst the impeachment managers is a smart move both for the country, for the substance and for the optics,” Phillips said, adding that Amash brings an array of qualifications: He’s an attorney, a constitutionalist and “the first and only member of the Republican conference, when he was a Republican, to show courage,” Phillips added.
