"And he may even go beyond what President Obama did in terms of violating our rights."

“I’ll be supportive when I think he’s right and I’ll be critical when I think he’s wrong,” Amash added of Trump. "I’ve been a critic of the Obama administration. There were many times when the Obama administration didn’t follow the Constitution, and I took them to task. I will do the same with the Trump administration.”

Amash also said he wouldn't shy away from breaking with fellow Republicans over Trump's policies, citing government spending as one potential division.

“I will take positions that sometimes the political establishment – my own party – won’t like,” he said. "I will take positions that sometimes the Trump administration won’t like. And sometimes I will take positions that the Democrats won’t like. My job is to be fair."

“We need to make sure we are keeping our debt under control,” Amash added. "Whenever you have one party controlling all of government, you tend to have less of a check on spending.”

Trump will enter the White House next month with Republican majorities in both the House and Senate behind him.

Many rank-and-file Republicans have rallied around the president-elect after their party’s often bruising presidential primary campaign.
