It took minutes, not hours, for top congressional Democrats to call on Trump's Attorney General Jeff Sessions to resign on Wednesday evening after the WaPo reported that he had allegedly met with the Russian ambassador in the months before the election, meetings that Sessions did not disclose during his confirmation hearings.

House Minority Leader Nancy Pelosi (D-Calif.) led the effort late on Wednesday night, accusing Sessions of "lying under oath" during confirmation proceedings about his contacts with the Russians.

"Jeff Sessions lied under oath during his confirmation hearing before the Senate. Under penalty of perjury, he told the Senate Judiciary Committee, 'I have been called a surrogate at a time or two in that campaign and I did not have communications with the Russians.' We now know that statement is false," Pelosi said in a statement.
