Comedian Stephen Colbert broke character at a House hearing on Friday, lamenting the poor treatment migrant workers face in the U.S.

Colbert, after spending most of the morning mocking a Judiciary subcommittee hearing, made an earnest plea for congressional assistance for migrant workers.

"Migrant workers suffer and have no rights," he said.

Colbert said he meant his appearance before the lawmakers to be an opportunity to speak out for "the least of our brothers," speaking briefly toward the end of the hearing in response to a question from Rep. Judy Chu (D-Calif.).

Colbert had spent most of the morning mocking lawmakers on the panel, having broken from his prepared remarks to deliver a comedic monologue.

Colbert told Rep. Lamar Smith (R-Texas), the ranking member of the Judiciary Committee, that he endorsed all GOP policies "without question," including the new "Pledge to America."

He also jabbed at Rep. Steve King (R-Iowa), the ranking member of the subcommittee, when he half-heartedly apologized for using the term "corn-packer" as a derogatory term for a gay Iowan.
