Hillary Clinton sharply criticized Attorney General William P. Barr, President Trump, members of the Republican Party and some findings of the Mueller report on Wednesday night in a wide-ranging interview in which she warned of continuing Russian efforts to interfere in United States elections.

Mrs. Clinton appeared on “The Rachel Maddow Show” on MSNBC just hours after the contentious hearing in which Mr. Barr took questions from the Senate Judiciary Committee on Robert S. Mueller III’s report. Among the things the 448-page report revealed was Mr. Trump’s fixation on targeting Mrs. Clinton as a subject for further investigation.

“I’m living rent free inside of Donald Trump’s brain, and it’s not a very nice place to be, I can tell you that,” said Mrs. Clinton, the former Secretary of State who was defeated by Mr. Trump in the 2016 election.

“When in doubt, go after me,” she said of the Republican Party’s strategy. “This is part of their whole technique to divert attention from what the real story is. The real story is the Russians interfered in our election. And Trump committed obstruction of justice. That’s the real story.”
