Presumptive Republican nominee Donald Trump is using Twitter to criticize the media.

In more than a dozen different tweets, the New Yorker called out the The New York Times, The Washington Post, CNN and The Hill.

Trump tells his more than eight million Twitter followers that the media is “on a witch-hunt against me. False reporting, and plenty of it – but we will prevail!”

Trump’s tweets began on Friday, calling out The Hill for a story it did about him and carbon tax.

.@thehill Your story about me & the carbon tax is absolutely incorrect—it is just the opposite. I will not support or endorse a carbon tax! — Donald J. Trump (@realDonaldTrump) May 13, 2016

On Saturday and again on Monday morning, Trump went after CNN.

Wow, @CNN is really working hard to make me look as bad as possible. Very unprofessional. Hurting in ratings – bad television! — Donald J. Trump (@realDonaldTrump) May 14, 2016

A political commentator for @cnn, which I no longer watch, said "Trump showed some weakness in the Repub Primaries." I set all-time record! — Donald J. Trump (@realDonaldTrump) May 16, 2016

Trump also used his Twitter account to walk back a report from The Washington Post, which quoted Trump surrogate Dr. Ben Carson revealing five of Trump’s vice presidential picks.

The @washingtonpost report on potential VP candidates is wrong. Marco Rubio and most others mentioned are NOT under consideration. — Donald J. Trump (@realDonaldTrump) May 16, 2016

Most of Trump’s tweets throughout the weekend came after the New York Times published a story about Trump and women on Saturday, titled, “Crossing the Line: How Donald Trump Behaved With Women in Private.” On Monday, a key source disputed the New York Times article during an interview on Fox and Friends.

The failing @nytimes wrote yet another hit piece on me. All are impressed with how nicely I have treated women, they found nothing. A joke! — Donald J. Trump (@realDonaldTrump) May 15, 2016

Everyone is laughing at the @nytimes for the lame hit piece they did on me and women.I gave them many names of women I helped-refused to use — Donald J. Trump (@realDonaldTrump) May 15, 2016

Why doesn't the failing @nytimes write the real story on the Clintons and women? The media is TOTALLY dishonest! — Donald J. Trump (@realDonaldTrump) May 15, 2016

Wow, I have had so many calls from high ranking people laughing at the stupidity of the failing @nytimes piece. Massive front page for that! — Donald J. Trump (@realDonaldTrump) May 15, 2016

Why did the failing @nytimes refuse to use any of the names given to them that I was so proud to have helped with their careers. DISHONEST! — Donald J. Trump (@realDonaldTrump) May 15, 2016

The media is really on a witch-hunt against me. False reporting, and plenty of it – but we will prevail! — Donald J. Trump (@realDonaldTrump) May 15, 2016

That was an amazing interview on @foxandfriends – I hope the rest of the media picks it up to show how totally dishonest the @nytimes is! — Donald J. Trump (@realDonaldTrump) May 16, 2016

The @nytimes is so dishonest. Their hit piece cover story on me yesterday was just blown up by Rowanne Brewer, who said it was a lie! — Donald J. Trump (@realDonaldTrump) May 16, 2016
