Rep. Justin Amash (R-Mich.), who last week became the first Republican to express support for an independent investigation into the Trump-Russia matter, said Wednesday that if the details reported this week are true, it could be grounds for impeachment.

According to the Hill, Amash added that “everybody gets a fair trial in this country.”

Amash, a member of the Freedom Caucus and one of Trump’s frequent GOP critics, was the first drop in what’s become a small but steady trickle of Republicans who have come out in support of some kind of an independent investigation — some, like Amash, spoke out right after Trump fired FBI director James B. Comey, a few others voiced concerns after the twin bombshells of Trump’s behavior in the Oval Office.

But these lawmakers are outliers, representing just a handful of the hundreds of Republicans in the GOP-controlled Congress — most of whom have either have not commented about this, or who have said another investigation is unnecessary.

Even before the special-investigation chatter, Amash was already a thorn in the side of the Trump administration.

Last month, White House social-media director Dan Scavino Jr. called Amash “a big liability” and called on the “#TrumpTrain” to defeat the Michigan Republican in his primary.
