A tea party activist is challenging U.S. House Speaker John Boehner (BAY'-nur) in the 2012 Republican primary.

The Cincinnati Enquirer (http://bit.ly/o5hTXQ) reports that David Lewis announced his candidacy on Friday.

Lewis, the father of a 2-year-old girl, says he plans on running on a single issue _ Boehner's support of a federal budget that provides funding to Planned Parenthood, which he calls "the largest killer of unborn babies in America."

Lewis tells the newspaper that he plans on running graphic anti-abortion ads against Boehner. He says that people will not reject abortion until they see abortion.

Boehner beat out two other candidates in the Republican primary for his congressional seat last year with 85 percent of the vote. His staff declined the newspaper's requests for comment.
