ROB LONGLEY: Republicans Use Constitutional Experts — and President’s Own Words — in Debate Over Immigration Decree.

“President Obama has stated over 20 times in the past that he doesn’t have the constitutional power to take such steps on his own — and has repeatedly stated that, ‘I’m not a king,’” Goodlatte said in his opening statement.

He then played a video showing a series of clips in which Obama insists he can’t unilaterally change or make immigration law.

He said the president’s 180-degree turn on the issue has lit the fuse of a “full-fledged” constitutional crisis.

“The Constitution is clear,” Goodlatte said. “It is Congress’ duty to write our nation’s laws and, once they are enacted, it is the president’s responsibility to enforce them.”

Indeed.
