While his Republican colleagues have largely held their tongues since Donald Trump won the presidential election, Rep. Justin Amash of Michigan called out the president-elect after Trump suggested people shouldn’t be surprised that his business interests could conflict with his position in the White House.

Amash, who called for Trump to end his candidacy after a 2005 video surfaced of him making lewd comments about women, took to Trump’s preferred communication platform, Twitter, to criticize him.

He was responding a Trump tweet Monday night that read, "Prior to the election it was well known that I have interests in properties all over the world. Only the crooked media makes this a big deal!"

Amash, who is part of a more libertarian wing of the House Republican conference, first endorsed Sen. Rand Paul in the presidential race and then Sen. Ted Cruz after Paul dropped out.

But Amash sounded a hopeful note after Trump won, tweeting that he looked forward to working together “to defend liberty.”
