Senate Minority Leader Mitch McConnell has officially filed his paperwork for re-election, and Kentucky's two other statewide-elected Republicans are lending their names to the effort.
McConnell's campaign says Sen. Rand Paul and state Agriculture Commissioner James Comer would sign McConnell's papers on Tuesday.
McConnell's campaign says it's releasing a new video that includes comments by Paul and Comer.
In the video, Paul praises McConnell's efforts to oppose the federal health-care overhaul and to push in support of a balanced budget amendment.
McConnell -- the state's longest-serving senator -- is seeking a sixth Senate term. He is facing a challenge in the GOP primary this spring from Louisville businessman Matt Bevin.
The Democratic front-runner in the race is Alison Lundergan Grimes, who is Kentucky's secretary of state.
