President Donald Trump has repeatedly called Robert Mueller’s sweeping investigation into Russian meddling in the 2016 election a “witch hunt.”

Critics of the president worry the investigation may be jeopardy after Jeff Sessions’ firing as attorney general.

Kat and Dennis McCann of New Orleans are among those participating in what's been dubbed “Nobody's Above the Law” protests across the country.

“I see this as a way to force and possibly remove Mueller and stopping the investigation all together,” Kat McCann said.

“Theoretically, the attorney general is supposed to represent the people of the United States,” Dennis McCann said.

The McCanns fear the next attorney general will be a Trump loyalist who will serve the president, rather than the rule of law.

U.S. Sen. John Kennedy (R-La.) said the president is entitled to surround himself with advisors of his choosing.

“I don't think Mr. Mueller ought to be fired. I think for the country's sake we ought to let this investigation be completed, but Mr. Mueller needs to wrap it up,” Kennedy said.

Kennedy also doesn't see a constitutional crisis with Sessions; firing.

“People in Washington, D.C. like to event a crisis every other Thursday. Sometimes more frequently than that. I don't think this is a crisis,” Kenney said.

In the meantime, people like the McCanns are putting Kennedy and Trump on notice: they are watching.

“Is it going to do any good? I don't know,” Dennis McCann said. “But it's just like Bob Dylan wrote, ‘How many times can a man turn his head and pretend he just doesn't see?’”
