(CNN) – Former presidential candidate Michele Bachmann did not deny Monday whether she was being vetted for the job of Mitt Romney's running mate.
"Whoever it is that he chooses to bring in as his V.P., it will be a highly competent person who could step in at a moment's notice and assume the responsibilities of the White House," the Minnesota congresswoman said on CNN's "Piers Morgan Tonight."
Pressed further if she was being considered for the gig, Bachmann, whose name has not been frequently mentioned as a potential contender, left it up to the presumptive GOP nominee and his team to make a comment.
"Well, that's something for the campaign to answer on," she said. "That's not for me to make that decision, and that announcement."
While veep-talk has certainly been a swirling force on the campaign trail in recent weeks, Romney has only confirmed his campaign was vetting Sen. Marco Rubio of Florida, though many more are expected to be on his list.
The former Massachusetts governor announced he was considering Rubio in mid-June after some Republicans grew upset over a report claiming the senator was not in the running.
Other potential candidates have kept mum on the veepstakes, refusing to say whether or not they may have a hat in the ring.
For her part, Bachmann was critical of Romney when the two competed for the Republican presidential nomination. As a candidate, Bachmann initially ran with large tea party appeal, frequently bucking what she described as the more establishment faction of the party that Romney represented.
The congresswoman did not endorse Romney until early May, several weeks after former Pennsylvania Sen. Rick Santorum dropped out of the race, a move that essentially locked up the nomination for Romney.
Asked repeatedly why she had held out in her support for Romney, Bachmann declined to go into specifics but maintained she was working "behind the scenes, bringing together all factions of our party."
