Special counsel Robert Mueller warned President Donald Trump's legal team that he was prepared to subpoena the commander-in-chief for testimony, The Washington Post reported Tuesday.


At the March 5 meeting, then-Trump attorney John Dowd was angered by the veiled threat.

“This isn’t some game,” Dowd reportedly argued. “You are screwing with the work of the president of the United States.”
