(CNN) - Kentucky Sen. Jim Bunning is maintaining his reputation for holding the most entertaining conference calls in Congress, telling reporters listening in to his latest teleconference Tuesday that Senate Minority Leader Mitch McConnell is a "control freak."
"McConnell is leading the ship, but he is leading it in the wrong direction," Bunning said of his fellow Kentucky senator, according to the Louisville Courier-Journal. "If Mitch McConnell doesn't endorse me, it could be the best thing that ever happened to me in Kentucky."
The embattled Bunning has openly butted heads with his party's leadership since declaring earlier this year his intention to seek a third Senate term. Both McConnell and the National Republican Senatorial Committee have been tepid on a reelection bid for Bunning, who narrowly escaped defeat in 2004 and is likely to face the same Democratic opponent next year.
In previous conference calls, Bunning has pledged to sue the NRSC if they support another Republican candidate, and that he doesn't "believe anything [NRSC Chairman] John Cornyn says."
Bunning, 77, has also hit back at reported statements from McConnell that the former baseball star is too old to seek another Senate term.
"Do you know Arlen Specter will be 80, has had four bouts with cancer and he still wants to run for the U.S. Senate?" Bunning told reporters on the call earlier this month. "And I'm being criticized at 77 and healthy for wanting to run for the U.S. Senate by certain leadership people in my party. Give me a break."
