Senator Ted Cruz has drawn both praise and scorn for comments made last Friday on the Senate floor. According to the Texas Tribune, Cruz upset some by calling Senate Majority Leader Mitch McConnell a liar.

“I have listened to the comments of my colleague, the junior senator from Texas, both last week and this week, and I would have to say that he is mistaken,” Cornyn said.

At issue: Cruz on Friday accused Senate Majority Leader Mitch McConnell — a Cornyn ally — of telling a “flat-out lie” to Senate Republicans over movement of legislation related to an obscure, controversial federal agency called the Export-Import Bank.

For Senate standards, it was a savaging comment.

Cruz defended his comments on Sunday.

“No member of this body should engage in ad hominem attacks directed at any member of this body, be they a Republican or be they a Democrat,” Cruz said.

“At the same time, I would note that it is entirely consistent with decorum, and with the nature of this body traditionally as the world’s greatest deliberative body, to speak the truth,” he added. “Speaking the truth about actions is entirely consistent with civility."

Cornyn took the floor immediately after Cruz. He backed McConnell’s procedural maneuvers that stifled a Cruz amendment on Iran. And Cornyn questioned the legitimacy of Cruz’s charges against McConnell.

“If the majority leader had somehow misrepresented to 54 senators what the facts are with regards to the Ex-Im Bank, I would suspect that you would find other voices joining that of the junior senator, but I hear no one else making such a similar accusation.”

“There was no misrepresentation made by the majority leader on the Ex-Im Bank,” Cornyn added.

On Monday's edition of The Chad Hasty Show, Republican political strategist Matt Mackowiak said he thought that Cruz may have hurt his future in the Senate.

Cruz’s impact as a U.S. Senator is going to be minimal going forward. You know, he’s going to be persona non grata within the Senate Republican leadership. And if you’re a conservative you may think that’s great, but if you’re a Texan, you know, you might be wondering what is Cruz going to be doing the rest of his Senate term.
