WATCH: NBC reporter ambushes Mueller outside Easter church service — Mueller immediately shuts him down

Despite Sunday being the holiest of days in the Christian tradition, an NBC reporter stalked special counsel Robert Mueller outside of his church on Sunday to confront him on camera about the investigation into Russia and President Donald Trump.

What happened?

NBC correspondent Mike Viqueira confronted Mueller as he attempted to get into his vehicle. Mueller was with his wife and had just left his Easter church service.

"Sir, can I ask you a couple questions? Will you testify before Congress, sir?" Viqueria asked, sticking his microphone in Mueller's face.

"Uh, no comment," Mueller responded.

"Are you sure about that sir?" Viqueria shot back. "If he were anybody but the president, would Mr. Trump be indicted, sir?"

Mueller continued to ignore Viqueria, but that didn't stop the reporter from peppering the former FBI director with questions about Trump.

"Sir, why didn't you make a recommendation to Congress one way or the other?" Viqueria asked. "Did the attorney general accurately characterize your positions on conspiracy and obstruction, sir?"

Mueller finally got in his car and left. He did not answer any of Viqueria's questions.

Viqueira later recapped the ambush on MSNBC, laughing at what he did and characterized Mueller as being "tight-lipped."
