A new HuffPost/YouGov poll finds that 48% of Republicans believe that up to 5 million people voted illegally in the last presidential election ― a claim that President Trump has repeatedly made, even though neither he nor anyone else has produced concrete evidence to show it’s true.

Just 17% said they do not believe that claim and 35% said they were unsure.

Sen. Marco Rubio (R-FL) told ABC News that he sees “no evidence” to support claims that the FBI used an informant to gather information on the Trump campaign, but that instead the federal probe was focused on “individuals with a history of links to Russia that were concerning.”

President Trump tweeted that the Russia probe has “devastated and destroyed” the reputations of people, continuing his weekend Twitter assault against the Robert Mueller investigation into Russian interference in the 2016 election, Politico reports.

Said Trump: “Who’s going to give back the young and beautiful lives (and others) that have been devastated and destroyed by the phony Russia Collusion Witch Hunt? They journeyed down to Washington, D.C., with stars in their eyes and wanting to help our nation. … They went back home in tatters.”

“Special counsel Robert Mueller’s investigators have obtained a presentation prepared by an Israel-based private intelligence firm that outlines ways in which Donald Trump’s 2016 election was helped by fake news and fake social-media accounts,” the Wall Street Journal reports.

“Mr. Mueller’s interest in the presentation suggests his investigation is focusing on the role of social-media manipulation during the 2016 campaign… The presentation consists of nine slides and was prepared by the Psy-Group, a firm that boasts of ties to elite Israeli intelligence agencies.”

New York Times: “With so many Democrats running, the party’s fear is that the vote will be splintered, allowing Republicans — who have fewer candidates — to dominate some primaries. The party and allied groups are spending more than $4 million on just three campaigns, intervening in one contest to prop up a favored candidate; attacking a Republican from the right in another; and even reminding people not to waste their votes on “ghost candidates” who have dropped out yet remain on the ballot.”

“The ‘top two’ system was meant to create incentives for political moderation in a state where about a quarter of the voters are independents, but it has created immense stakes for Democrats: They need to win 23 seats to take back the House, and party officials believe the path runs through the seven competitive California districts, all of which Hillary Clinton carried in 2016.”
