Senate races

Former state Treasurer Shane Osborne is the first Republican to run for retiring Sen. Mike Johanns' (R-Neb.) seat.

New web video comes one day after the Senate Republican leader sent a fund-raising email on behalf of Gabriel Gomez.

Curtis Morrison, one of the two men accused by Sen. Mitch McConnell (R-Ky.) of secretly recording his private conversation with aides, admitted he was behind the recording and said a grand jury is investigating the situation.

"Here's the latest: An assistant U.S. attorney, Bryan Calhoun, telephoned my attorney yesterday, asking to meet with him next Friday as charges against me are being presented to a grand jury," Morrison wrote on the website of progressive magazine Salon.

In the piece, Morrison adds that he does not regret making and releasing the recording. It revealed the details of a meeting between McConnell and his aides during which they outline potential lines of attack against actress Ashley Judd, who was then considering a bid, and Kentucky Secretary of State Alison Lundergan Grimes, who has not yet decided on the race.
