Michele Bachmann has spent three days trumpeting tonight’s tele-town hall featuring billionaire Donald Trump, but the guest of honor didn’t even know the conference call was scheduled to take place until a reporter clued him in this morning.

Trump said he had agreed to the teleconference with Bachmann supporters, which the Minnesota congresswoman has been promoting as fundraising device, but didn’t know it was happening this evening until he was told by the anchors of “Fox and Friends.”

“It’s called a modern-day town-hall meeting, right? And I said, ‘I guess I could.’ I didn’t even know I was doing it till you just told me,  but that’s OK,” Trump said Monday.

Trump said Bachmann asked him to participate in the call “not [as] an endorsement,”  but a “favor.”

Trump, who toyed with seeking the GOP nomination himself, has become an unofficial kingmaker this election cycle, with four candidates —  Bachmann, Herman Cain, former Mass Gov. Mitt Romney and Texas Gov. Rick Perry — visiting his New York offices to pay homage.

Bachmann, who last week released lackluster fundraising totals for the third quarter, sent an email to supporters asking them to participate in the call and contribute to her campaign.

“This is an incredible opportunity for you and everyone from Team Bachmann to hear from a businessman who knows firsthand that Barack Obama’s failed policies are crippling our nation’s job creators,” Bachmann wrote in an email to supporters.
