(CNSNews.com) – President Trump, still fuming about Democrats’ efforts to undermine his last campaign with the “dossier,” is now warning they’ll try to do it again.

In two tweets on Tuesday morning, the president railed against “13 Angry Democrats,” a reference to Special Counsel Robert Mueller’s team:

— “The 13 Angry Democrats (plus people who worked 8 years for Obama) working on the rigged Russia Witch Hunt, will be MEDDLING with the mid-term elections, especially now that Republicans (stay tough!) are taking the lead in Polls. There was no Collusion, except by the Democrats!”

— “Why aren’t the 13 Angry and heavily conflicted Democrats investigating the totally Crooked Campaign of totally Crooked Hillary Clinton. It’s a Rigged Witch Hunt, that’s why! Ask them if they enjoyed her after election celebration!”

The Wall Street Journal reported months ago that Andrew Weissmann, one of Robert Mueller’s investigators, was at Hillary Clinton’s headquarters on election night, preparing to celebrate a victory that never happened. Other members of Mueller’s team have contributed to Democrat campaigns.

And the Washington Post reported that “publicly available voter registration information shows that 13 of the 17 members of Mueller’s team have previously registered as Democrats, while four had no affiliation or their affiliation could not be found.” The Post also found that 9 of the 17 made political donations to Democrats and 6 donated to Hillary Clinton.

In a third tweet on Tuesday morning, President Trump quoted Fox News contributor Mollie Hemingway: “This investigation involved far more surveillance than we ever had any idea about. It wasn’t just a wiretap against a campaign aide…it was secretly gathering information on the Trump Campaign…people call that Spying…this is unprecedented and scandalous.”

He apparently ended the series of tweets by saying, “Sorry, I’ve got to start focusing my energy on North Korea Nuclear, bad Trade Deals, VA Choice, the Economy, rebuilding the Military, and so much more, and not on the Rigged Russia Witch Hunt that should be investigating Clinton/Russia/FBI/Justice/Obama/Comey/Lynch etc.”
