President Trump tweeted his frustration about a newly released poll by Fox News, which he claimed was biased toward Democrats.

"The @foxnewPolls, always inaccurate, are heavily weighted toward Dems," Trump said Sunday. "So ridiculous - same thing happened in 2016. They got it all wrong. Get a new pollster!"

The president has previously criticized Fox for their polling, slamming network data showing nearly half of American voters support impeachment last month.

"The Fox polls have always been lousy,” he said after polls showed an even split on support for impeachment. “I tell them they ought to get themselves a new pollster."

The president also slammed Fox in October via Twitter, saying of the pollster for the cable news network, "They suck."

"From the day I announced I was running for President, I have NEVER had a good @FoxNews Poll. Whoever their Pollster is, they suck. But @FoxNews is also much different than it used to be in the good old days," Trump said. "@FoxNews doesn’t deliver for US anymore. It is so different than it used to be. Oh well, I’m President!"

...Court Justice & I turned him down (he’s been terrible ever since), Shep Smith, @donnabrazile (who gave Crooked Hillary the debate questions & got fired from @CNN), & others, @FoxNews doesn’t deliver for US anymore. It is so different than it used to be. Oh well, I’m President! — Donald J. Trump (@realDonaldTrump) October 10, 2019

The latest polling data from Fox shows a 1% increase from late October in favor of impeaching and removing Trump from office. Those who feel he should be impeached but not removed and those against impeachment did not change, despite multiple days of hearings and witness testimony in Congress.
