Susan Collins, the Republican Maine senator seen by Democrats as vulnerable in November’s midterm election, has revealed a decades-old medical condition she said affects her appearance, but not her ability to do her job.

Collins, 73, told News Center Maine, an NBC affiliate, that she has a benign essential tremor she treats with medication, which sometimes causes her hands, arms and head to tremble.
