Thursday, Sen. Ted Cruz argued against nominating Loretta Lynch as Attorney General, calling her unsuitable for the job.

"I wanted to see a new Attorney General who would be faithful to law, but her answers made that impossible," Cruz said of Lynch's confirmation hearing, saying in a 10-minute speech on the Senate floor that she had "embraced the lawlessness" of Eric Holder's tenure.

Then he missed the final vote on her nomination -- the only senator to do so.

"He voted for cloture, that was the vote that mattered," said Cruz spokesman Rick Tyler. "He made the case against her, he voted against her in cloture and he didn’t prevail."

Why exactly did Cruz miss the final vote? Tyler wouldn't say. Cruz attended a Dallas fundraiser Thursday night before traveling to Las Vegas, where he will attend a meeting of the Republican Jewish Coalition meeting.
