NEW YORK (AP) — The United Farm Workers union says Stephen Colbert will visit Capitol Hill on Friday to testify at a U.S. House committee hearing on farm workers who are illegal immigrants.

Colbert's will appear as an expert witness. He has focused on the UFW's "Take Our Jobs" campaign on his nightly show on Comedy Central, "The Colbert Report." He had spent a day last month picking vegetables on a farm in upstate New York.

The UFW launched the "Take Our Jobs" campaign in June to invite U.S. citizens and legal residents to replace illegal immigrants who work on farms.

The hearing is before the House Judiciary Committee's immigration subcommittee.
