On Thursday, President Donald Trump took to Twitter to lash out at Michigan Rep. Justin Amash, who announced hours before that he was "declaring his independence" from the Republican Party:

Amash, a staunch libertarian who was elected in the Tea Party wave of 2010, has been increasingly at odds with the president. Following former special counsel Robert Mueller's report, he became the only Republican to say Trump committed impeachable acts, arguing that the report contained ample evidence the president obstructed justice.

The tension with his colleagues led him to abandon the House Freedom Caucus, the far-right congressional faction he helped found in 2015.
