Tea Party Patriots Action has released an ad that seems aimed at encouraging President Donald Trump to fire Deputy Attorney General Rod Rosenstein.

While Rosenstein might be a Republican appointed by former GOP President George W. Bush and kept on by Trump, that isn't enough for the fundamentalist wing of the GOP. The fact that former President Barack Obama and former Secretary of State Hillary Clinton aren't in handcuffs seems to be the nail in the coffin for his career.

The ad alleges that instead of following the rule of law, Rosenstein is working for the so-called "deep state."

The Democratic leadership in the Senate has warned that firing Rosenstein would start the ball rolling into a "Constitutional crisis."

"We write to inform you that we would consider such an unwarranted action as an attempt to obstruct justice in the Russia investigation. Firing Rod Rosenstein, [Department of Justice] Leadership, or Bob Mueller could result in a constitutional crisis of the kind not seen since the Saturday Night Massacre," Democrats wrote in a letter to the president.

Republicans have similarly warned the White House not to fire Rosenstein.
