Sen. Barbara Mikulski (D-Md.) will have served in the Senate for 25 years when she begins her fifth term next week.
Sen. Barbara Mikulski (D-Md.) is on her way to becoming the longest-serving woman in the history of the U.S. Senate. Mikulski will be sworn in for her fifth term next week. The 74-year-old Democrat joined the Senate back in 1986. This week, she'll surpass the longstanding record of the late Republican Sen. Margaret Chase Smith (Maine) who held her seat for 24 years.
Mikulski serves as the dean of the women in the Senate, mentoring other women senators when they first take office. She says she is most proud of helping to pass the Spousal Anti-Impoverishment Act while in the Senate. The legislation helps keeps seniors from going bankrupt while paying for a spouse's nursing home care.
She also served as a congress member for 10 years. Before that she was a member of the Baltimore City Council.
