Rep. John Dingell (D-Mich.), the dean of the House of Representatives, told The Hill on Wednesday that his wife, Debbie, is considering running for Senate.

Dingell's comments mark the first time anyone close to Debbie Dingell has openly said she is weighing a Senate bid, though she's been actively laying the groundwork for a campaign. Sources close to Debbie Dingell have discussed her as a potential candidate for a few weeks.

"She's getting lots of offers of support and some of them are from folks who are fairly high-placed in the system. She's also getting a lot of support from ordinary citizens. She is at this time making up her mind," Dingell told The Hill.

Debbie Dingell, a Democratic National Committee member and former government affairs executive for General Motors, has long been a major behind-the-scenes power player in the Michigan's Democratic Party.
