Rep. Michele Bachmann released a doctor's note Wednesday that says her migraine headaches are "infrequent," the latest attempt by her presidential campaign to try and move past the story about her health.

The letter, from Congress' attending physician Brian Monahan, also says Bachmann is able to control her migraines with medication and that she does not take daily medication.

"Your migraines occur infrequently and have known trigger factors of which you are aware and know how to avoid," Monahan wrote. "When you do have a migraine, you are able to control it well with as-needed sumatriptan and odansetron."

After The Daily Caller published a story late Monday that said Bachmann suffered from "incapacitating" headaches, she released a statement saying her migraines would not impede her ability to be president.

But questions continued about the extent of her condition, which has landed her in the hospital. When former Minnesota Gov. Tim Pawlenty was asked about Bachmann's migraines in Iowa Wednesday, he told reporters, "All of the candidates I think are going to have to demonstrate they can do all of the job all of the time."

While he declined to address Bachmann's migraines specifically, Pawlenty's comment stood in contrast to Mitt Romney, who said Wednesday: "There's no question in my mind that Michele Bachmann's health is in no way an impediment to her being able to serve as president."
