"I haven't yet made a decision yet about who I will endorse or if I will endorse before the nominee is chosen," Bachmann told Martha MacCallum during a Fox News interview on Wednesday. "I want to be a unifying voice. I want to bring together the tea party, the establishment, evangelicals, because we have to also bring in independents and disaffected Democrats. We have to beat Obama."
The rumors about a possible endorsement went into high gear because of Romney's Wednesday schedule which has him attending a grassroots rally in Bachmann's home state of Minnesota. There were even some reports that operatives from the two campaigns were in talks about a possible endorsement.
An endorsement from Bachmann could prove to be very useful for Romney since the congresswoman is a very popular figure among the hard core conservatives that Romney traditionally has a difficult time courting.
Bachmann released a statement later on Wednesday reiterating the sentiments she first articulated on Fox News.
"Let me be absolutely clear -- there are absolutely no negotiations between me and the Romney campaign regarding any pending endorsement of Governor Romney," said Bachmann. "I continue to speak with all the candidates and plan on uniting behind the presumptive nominee."
