President-elect Donald Trump is further excoriating CNN, taking time to mock the network on Twitter for its supposed support of Hillary Clinton and for the tone of its coverage since she lost the election.

“I thought that CNN would get better after they failed so badly in their support of Hillary Clinton however, since election, they are worse!” he wrote on Tuesday morning.

Last night, Trump also shared his opinion on the network.

“CNN is so embarrassed by their total (100%) support of Hillary Clinton, and yet her loss in a landslide, that they don’t know what to do,” he wrote on Twitter.

Trump also retweeted several criticisms of the network and one reporter, Jeff Zeleny, who was an embedded reporter on the failed Hillary Clinton presidential campaign.

Twitter critics of Zeleny lashed out at a CNN report condemning Trump’s accusations of voter fraud.

“What PROOF do u have DonaldTrump did not suffer from millions of FRAUD votes? Journalist? Do your job! CNN,” one person wrote in a tweet that was featured by Trump. Another critic called Zeleny a “wannabe journalist” that didn’t have evidence that Trump was incorrect about voter fraud.
