ST. PAUL, Minn. -- As reports swirled that Michele Bachmann is bothered by migraines, a doctor's letter issued Wednesday describes the Republican presidential candidate's headaches as occurring "infrequently" and controlled by prescription drugs.
Written at Bachmann's request, the letter from Dr. Brian Monahan, the attending physician in Congress, is the latest step in her effort to combat reports that her severe headaches have hindered her work in Congress and could pose problems if she were president.
One of her rivals, former Massachusetts GOP Gov. Mitt Romney, came to her defense. "There is no question in my mind that Michele Bachmann's health is in no way an impediment to her being able to serve as president," he said during a Los Angeles appearance.
Monahan's letter said Bachmann has undergone detailed lab work and brain scans that are normal. Her as-needed drug regimen includes two commonly prescribed migraine medicines, sumatriptan and odansetron. It wasn't clear if Monahan had personally attended to Bachmann.
Bachmann's campaign has declined to release detailed medical reports.
