Rep. Maxine Waters, D-Calif., on Wednesday tweeted a poem about special counsel Robert Mueller jailing members of the Trump campaign.

“A message to Mueller: Stay strong and stand tall. Continue to investigate them all. You are indeed answering the people's call. The Kremlin Klan is going to fall. Around you the Democrats are building a wall. We look forward to the day, to prison they will all be hauled,” the California Democrat said on Twitter Wednesday afternoon.

Mueller was appointed in May to lead the Department of Justice’s investigation into Russian meddling in the 2016 presidential election and possible collusion with the Trump campaign.

Though Trump has called the investigation a “witch hunt” and GOP lawmakers have accused the probe as being politically biased, the White House has made it clear on numerous occasions that Mueller will not be removed from the position.

So far, Mueller has convicted or indicted four members of the Trump campaign and administration: Michael Flynn, George Papadopoulos, Paul Manafort, and Rick Gates.

In an interview last week with the New York Times, Trump said he thinks Mueller will be “fair” to him.
