New York University journalism professor Talia Lavin says Rep. Dan Crenshaw can be summed up in two words: “Captain s—head.”

The academic, who falsely claimed an Immigration and Customs Enforcement analyst (and war veteran) Justin Gaertner had a Nazi “Iron Cross” tattoo, is back in the spotlight with 9/11 comments aimed at the Texas Republican — a Navy SEAL veteran who lost his eye in service to the nation.

“The real victim, captain s–head, speaks,” Ms. Lavintweeted as controversy swirled around Rep. Ilhan Omar’s framing of the 9/11 terrorist attacks as “some people did something.”

Mr. Crenshaw said the Minnesota Democrat’s tone and delivery while speaking at a recent Council on American-Islamic Relations event were “unreal.”

Similarly, he said Rep. Alexandria Ocasio-Cortez’s decision to question his dedication to 9/11 victims was “a new low in partisanship dishonesty.”

“I watched in disbelief as some covered for Omar by coming after me with lies absurd claims that I don’t support 9/11 victims,” he tweeted Aug. 12. “What a disgusting, dishonest tactic. Why turn this into a political football?”

Ms. Lavin’s rhetorical jab at the combat veteran was reported by the educational watchdog Campus Reform on Monday.

“I should respect his rank,” she later added, the website reported. “His name is lieutenant commander sh—head.”

Regarding her erroneous 2018 claim about Mr. Gaertner (who lost both legs in an IED attack), she ultimately deleted her tweet “so as not to spread misinformation.”

Mr. Gaertner has a “Titan 2” tattoo on his left elbow in honor of the platoon he fought with while in Afghanistan.
