From Washington Post:
Sen. Barbara Mikulski (D-Md.), who has served in Congress longer than any woman in history, announced Monday that she will retire after five terms in office, shocking Democrats in her state and setting off an immediate scramble to replace her.
It doesn’t look like Sen. Mikulski is going out quietly though.
Mikulski said she decided against seeking a sixth term because she wanted to focus the next two years on helping her constituents, rather than spending her energy on another political campaign.
“Do I spend my time raising money or do I spend my time raising hell?” she said at the news conference. “Remember, for the next two years, I will be here, working the way that I do.”
