Mueller’s probe gets only a glancing reference in the articles of impeachment themselves. But Democrats — including Pelosi — have repeatedly leaned on the foundation Mueller built to help justify calls to remove Trump from office.

In short, Mueller is the Old Testament of Trump scandals, Ukraine is the New Testament.

“We’re not moving with speed. What was it, 2½ years ago that they initiated the Mueller investigation,” Pelosi said Tuesday when asked about GOP complaints over the rapid pace of the impeachment proceedings. “This has been going on for a very long time.”

And Democrats are still connecting Mueller to impeachment — at least paying lip service to his investigation, even if they’ve largely kept it out of the articles themselves. Democrats intend to expound on Mueller’s evidence in a lengthy report that will accompany the articles of impeachment when they’re voted out of the Judiciary Committee later this week.
