A House Foreign Affairs subcommittee hearing ended abruptly Tuesday after Rep. Keith Self (R-Texas) referred to Rep. Sarah McBride (D-Del.), the first transgender person elected to Congress, as “mister.”

Self, who chairs the Subcommittee on Europe, introduced McBride as “the Congressman from Delaware” during a hearing on arms control and U.S. assistance to Europe. McBride responded by calling Self “Madam Chair.”

As McBride delivered her remarks, Ranking Member Bill Keating (D-Mass.) interjected, asking Self to repeat his introduction.

“Mr. Chairman, you are out of order,” Keating said. “Mr. Chairman, have you no decency? I mean, I’ve come to know you a little bit, but this is not decent.”
