Hillary Clinton’s campaign is pushing back against reports of a personnel shake-up as the Democratic presidential candidate enters Tuesday’s New Hampshire primary the underdog. 

The speculation was kicked up Monday when Politico published a story saying Clinton isn't happy with her current campaign’s handling of her 2016 bid and is considering staffing and strategy changes.

Clinton’s rival Vermont Sen. Bernie Sanders has been gaining ground in several national polls, and leads virtually every New Hampshire poll. Clinton barely squeaked out a win against Sanders in the Iowa caucuses last week. 

The Clinton campaign is giving mixed messages over what might come next. 

"No shakeup coming," a Clinton official told Fox News. 

But while Clinton also said Monday she has “no idea what they’re talking about or who they are talking to” regarding the Politico piece, she did acknowledge her campaign is “going to take stock."

Reports indicate the campaign may be looking more to add staff -- rather than fire people. And Clinton suggested in the interview with MSNBC that her current team will stay. 

"It’s going to be the campaign that I’ve got. I’m very confident in the people that I have," she said. 

Clinton’s campaign chairman John Podesta also dismissed the shake-up rumors in a tweet.

“There is zero truth to what you may be reading. It’s wrong. Hillary stands behind her team, period,” he tweeted. 

Though Podesta says her staff is staying put, candidate Clinton has a history of eyeing staff shakeups and realignments in tough races.

In 2008, Clinton replaced Patti Solis Doyle, her campaign manager, with Maggie Williams, who had been Clinton’s chief of staff when she was first lady. Doyle was replaced after then-Sen. Barack Obama beat Clinton in Nebraska, Louisiana, Washington and in the U.S. Virgin Islands.   

While defending her campaign, the former secretary of state and New York senator did acknowledge she will be assessing what works and what doesn’t ahead of the South Carolina primary later this month.

"We’re moving into a different phase of the campaign. We’re moving into a more diverse electorate. We’re moving into different geographic areas. So, of course it would be malpractice not to say, 'OK, what worked? What can we do better? What do we have to do new and different that we have to pull out?,'" Clinton said on “The Rachel Maddow Show.”

Some analysts say Sanders' momentum has thrown the Clinton camp for a loop.

In January, Sanders raised $20 million while Clinton raised $15 million.
