We knew this was coming.

Paul Manafort, the former chairman for Donald Trump’s presidential campaign, has been subpoenaed to appear before the Senate Judicial Committee.

From the Washington Times:

Committee Chairman Charles E. Grassley, a Republican, and ranking Democrat Sen. Dianne Feinstein said they were fed up with delays and restrictions Mr. Manafort was trying to impose on their investigation, so they will compel him to appear.

“Mr. Manafort, through his attorney, said that he would be willing to provide only a single transcribed interview to Congress, which would not be available to the Judiciary Committee members or staff,” the two senators said. “While the Judiciary Committee was willing to cooperate on equal terms with any other committee to accommodate Mr. Manafort’s request, ultimately that was not possible.”

Those issues the committee are looking into involve Manafort’s work lobbying for foreign governments, and of course, what he knows about any possible attempts by the Russian government to interfere in the 2016 election.

Manafort is scheduled to appear on Wednesday.
