Former Minnesota congresswoman and 2012 Republican Presidential candidate Michele Bachmann said she is considering a run for Al Franken's Senate seat.

Background: Franken is officially resigning from Congress on Tuesday following a string of sexual misconduct allegations, with Minnesota's Democratic Lt. Gov. Tina Smith to take over the seat on Wednesday. Smith plans to run for the remaining two years of Franken's term in a special election in November.

Bachmann told televangelist Jim Bakker last week that she has received calls about the race and is praying on whether to return to Washington at a time when "the swamp is so toxic."

Key quote: "There's also a price you pay and the price is bigger than ever because the swamp is so toxic ... My husband and I aren't money people. And that's the thing."
