California congresswoman Maxine Waters isn’t letting up on her push to impeach Trump anytime soon.

Her resolve was evidenced yet again on Wednesday morning when she tweeted out a heartwarming poem dedicated to lawyer Robert Mueller who is also the lead special counsel in the investigation into Trump’s alleged ties to Russia. Mueller, a former FBI director, has been sued by former Trump campaign chair Paul Manafort. He claims charges bought against the campaign by Mueller weren’t within the realm of his authority.

“A message to Mueller: Stay strong and stand tall,” Waters wrote in response to the lawsuit. “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 congresswoman has been leading a campaign to impeach the President since his inauguration.
