And Maryland Democratic Senator Barbara Mikulski, the longest-serving woman in congressional history, has announced she will not seek re-election next year. Mikulski said she wanted to spend her remaining time in the Senate working for her constituents, instead of fundraising.

Sen. Barbara Mikulski: “I had to decide how I would spend my time—fighting for my job or fighting for their job? Do I spend my time raising money, or do I spend my time raising hell?”

Senator Mikulski has served in Congress since 1977, spearheading measures for fair pay and coverage of women’s preventive healthcare, and paving the way for women to wear pants on the Senate floor.
