WASHINGTON (Reuters) - Rep. Barney Frank said on Sunday he will put together an economic stimulus bill when Congress returns to session after the November elections, while a key Republican said he would support the effort.

Frank, chairman of the House of Representatives Financial Services Committee, said on ABC television that he would begin work on the stimulus bill in November in a "lame duck" session.

Rep. Roy Blunt, the Missouri Republican who serves as House minority leader, said he would support a stimulus plan if it did not include a massive public works program and budget bailouts for states that overspent on health care and other social programs.

"A stimulus plan that makes sense is something that i'll be helpful with," Blunt said, also on ABC television.
