GOP Rep. Dan Lungren (Calif.) may challenge House Minority Leader John Boehner (Ohio) for the top spot in the Republican Conference, GOP insiders said.
Lungren's office would not comment on Thursday other than to say that he will have an announcement today.
Lungren would be a long-shot to defeat Boehner, or win any other leadership post. Lungren served in Congress for a decade starting in 1978 before leaving Capitol Hill to become California attorney general. After eight years in that post, he unsuccessfully ran for governor in 1998. Lungren was then re-elected to the House in 2004.
