President Donald Trump's re-election campaign has reportedly fired some of its pollsters after internal polls, showing Trump struggling against former Vice President Joe Biden in key 2020 states, were leaked, according to multiple reports. Trump has disputed the findings of those polls.

A top adviser said three of the campaigns five pollsters are being let go "to prevent further disclosure of survey data," according to The New York Times.

Multiple news outlets have reported that internal polls, taken in March, show Trump not only is losing to Biden in battleground states vital to his re-election, but he's in a tight battle in states that are typically Republican strongholds.

The Times reports the Trump campaign's polls show Trump trailing Biden by double digits in Michigan, Wisconsin, and Pennsylvania. Trump won those states by combined 77,000 votes in 2016, helping him to the electoral college victory over Hillary Clinton.

ABC News reports the polling finds Trump leading Biden by two points in Texas, a normally reliable Republican state.

Trump reportedly disputed the reported poll results last week, calling them "fake polls." He said his campaign is winning in every state that it polled, including "very big" leads in Texas, Ohio and Florida.

The president doubled down on that in a Monday morning tweet.

"Only Fake Polls show us behind the Motley Crew. We are looking really good, but it is far too early to be focused on that. Much work to do! MAKE AMERICA GREAT AGAIN!" Trump tweeted.

Brad Parscale, Trump's campaign manager, said the polling is "ancient" and more recent polling finds a huge swing in Trump's favor, according to ABC News. Parscale cites the release of Robert Mueller's report into Russian election interference, and far-left policy positions by some Democratic presidential candidates as the reason for this.

Trump's re-election campaign kickoff rally will be held Tuesday in Orlando, Fla.
