Sen. Dick Durbin announced Tuesday he underwent a heart procedure to correct an abnormal heart rhythm, and used it as a chance to attack Republicans for trying to repeal Obamacare.

Durbin accused Republicans in a statement of seeking to "cut funding for medical research and take away health insurance for millions of Americans."

Durbin, D-Ill., said the outpatient procedure he had was considered minor and would correct an atrial flutter discovered during a routine physical. "I anticipate this tune up will give my classic roadster more miles of reliable service," Durbin said.

He warned that Republicans considering repealing Obamacare "should remember that all of us are only a diagnosis away from needing the best care for ourselves and the people we love."

Durbin will not return to work in the Senate this week, he said.
