Divorcing: Connie Mack and Mary Bono Mack. In the classic dump-bad-news-on-a-holiday-weekend, the former House members announced Friday that their six-year marriage is over. The couple released a statement saying they have “nothing but respect and admiration for each other,” reports the Tampa Bay Times, and gave no reason for the split.

The two Republicans caused a sensation when they began dating In 2005 while both serving in Congress — he from Florida, she from California. Bono, now 51, was the glamorous widow of the late singer/politician Sonny Bono; Mack, 45, the fourth generation of the respected Mack dynasty. The two married in 2007– her third, his second — becoming only the third married couple to serve in Congress together. Democrats Andrew Jacobs and Martha Keys were the first in the 1970s; followed by Republicans Bill Paxon and Susan Molinari in the 1990s.

Both Mack and Bono lost their election bids last November: Mack was defeated in his Senate race; Bono failed in her reelection bid. Each has joined a Washington lobbying firm, but not the same one — which, given their news, could have been awkward.
