Not unprecedented. Already well established.
McClintock’s glass house cracked back when he was one of four GOP members of Congress to vote against the motion to impeach Homeland Security Secretary Alejandro Mayorkas. In a 214-216 vote, three Republicans joined all Democrat House members in voting “No,” and a fourth Republican voted “No” based on procedural reasons.
In defense of his “No” vote, McClintock said that the impeachment effort is “…bad politics and bad policy. The problem is that they fail to identify an impeachable crime that Mayorkas has committed”.
McClintock wrote. “In effect, they stretch and distort the Constitution in order to hold the administration accountable for stretching and distorting the law.” (Source)
Apparently, to McClintock, intentionally maintaining an open southern U.S. southern border is not a crime. He seems to require that an “impeachable crime” can only be a sin of commission and not one of omission. I.e., Mayorkas can’t be impeached for what he didn’t do.
McClintock misses this truth:
When Mayorkas took his Oath of Office he pledged to uphold the laws of the United States Federal Government. But he has not done so. And, by indirectly sanctioning Mayorkas’ offenses, McClintock becomes complicit in his commission of crimes.
