Sen. Bernie Sanders told CNN on Thursday that he felt symptoms weeks ahead of his heart attack that he "should have paid more attention" to, and he will release his medical records "at the appropriate time."

SANDERS: "what I do kick myself a little bit about, and I hope people understand this and hear this, is that I should have paid more attention to some of the symptoms that were occurring. You know, when you do 4 rallies a day and you run all over the country, you get tired, everybody would get tired. But I was more tired than I usually have been, had more trouble sleeping than ordinarily. Occasionally, I would be up there at the podium and I would feel a little bit unsteady. You know, one time I was just lifting, literally holding the mic up to my mouth and my arm hurt. I should have paid more attention to those symptoms. So, I hope that people learn from my mistake."

CNN's SANJAY GUPTA: "It's such an important point, the symptoms you're describing may not be classic sort of symptoms, but left arm pain, some of this stuff were indicators. In retrospect, how long had you had symptoms, Senator?"

SANDERS: "I think, probably, it's hard to say, because, as I said, when you're running around the country, you're tired. What else is new, you're going to be tired. I would say several weeks, anyhow, and I should have paid more attention."

The big picture: Sanders has been recovering from a heart attack that has taken him off the campaign trail. While he originally suggested he would be slowing the pace of his 2020 presidential campaign, he since said he "misspoke," and told Gupta he plans to run a "vigorous campaign."

At least 11 Republican congressional nominees have publicly supported or defended the QAnon conspiracy theory movement or some of its tenets — and more aligned with the movement may still find a way onto ballots this year.

Why it matters: Their progress shows how a fringe online forum built on unsubstantiated claims and flagged as a threat by the FBI is seeking a foothold in the U.S. political mainstream.

Senate Judiciary Chairman Lindsey Graham (R-S.C.) tweeted Sunday that he will grant Democrats' request to call former special counsel Robert Mueller to testify before his committee.

The big picture: The announcement comes on the heels of Mueller publishing an op-ed in the Washington Post that defended the Russia investigation and conviction of Roger Stone, whose sentence was commuted by President Trump on Friday.
