WASHINGTON (AP) - Minnesota congresswoman Michele Bachmann says she will not run for another term in the U.S. House.

The tea party favorite, who ran for the Republican presidential nomination last year, announced her decision on her website Wednesday morning.

Bachmann says her decision not to run again in 2014 was "not influenced by any concerns about ... being re-elected."

She also says recent inquiries into her 2012 presidential campaign did not affect her decision.

Bachmann promises to "continue to work overtime for the next 18 months in Congress defending ... Constitutional Conservative values."

Bachmann's surprise announcement that she won't seek a fifth term has her opponent saying that she "read the tea leaves."

Jim Graves is the Democrat who nearly beat Bachmann in November. He says he thinks Bachmann heard a message in last fall's close race.

Graves says voters are looking for someone who has more of a business background and understands the economy. Graves is a businessman who built his wealth in the hotel business.

Graves was planning a second run against Bachmann. He says he has no idea who his new opponent will be.
