Fox News host Tucker Carlson doesn’t criticize Donald Trump very often, but he did so on Thursday night after the president suggested taking guns away from potentially dangerous people before due process.

“Imagine if Barack Obama had said that,” Carlson said. “Just ignore due process and start confiscating guns.”

Carlson said Obama would’ve been “denounced as a dictator” for making such a comment.

“We would have denounced him first, trust me,” Carlson said. “Congress would be talking impeachment right now. Some would be muttering about secession.”

Carlson also had a warning for Trump about Constitutional rights:

“Those rights are what makes us citizens and not mere subjects of the powerful, and the president needs to be reminded of that. Maybe we all do once in a while. If voters wanted that kind of government, they could have voted Democrat, and actually they still have a chance to vote Democrat in the midterms, which he should keep in mind.”

It was the second time in recent months that Carlson had broken with the president. In January, Carlson called out Trump for indicating that he would be willing to protect young undocumented immigrants, who are also known as dreamers. Noting that Trump’s campaign platform was tough on immigration, Carlson asked: “So what was the point of running for president?”

1994: The Violent Crime Control and Law Enforcement Act

The Violent Crime Control and Law Enforcement Act, signed into law by President Bill Clinton in 1994, instituted a ban on 19 kinds of assault weapons, including Uzis and AK-47s.

2004: Law Banning Magazines Holding More Than Ten Rounds Of Ammunition Expires

In 2004, ten years after it first became law, Congress allowed a provision banning possession of magazines holding more than ten rounds of ammunition to expire through a sunset provision. Brady Campaign President Paul Helmke told HuffPost that the expiration of this provision meant that Rep.

Gabrielle Giffords And Trayvon Martin Shootings

Gun control advocates had high hopes that reform efforts would have increased momentum in the wake of two tragic events that rocked the nation. In January of 2011, Jared Loughner opened fire at an event held by Rep. Gabrielle Giffords (D-Ariz.), killing six and injuring 13, including the congresswoman. Resulting attempts to push gun control legislation proved fruitless, with neither proposal even succeeding in gaining a single GOP co-sponsor. More than a year after that shooting, Florida teenager Trayvon Martin was gunned down by George Zimmerman in an event that some believed would bring increased scrutiny on the nation's Stand Your Ground laws. While there has been increasing discussion over the nature of those statutes, lawmakers were quick to concede that they had little faith the event would effectively spur gun control legislation, thanks largely to the National Rifle Association's vast lobbying power.

Colorado Movie Theater Shooting

In July of 2012, a heavily armed gunman opened fire on theatergoers attending a midnight premiere of the final film of the latest Batman trilogy, killing 12 and wounding scores more. The suspect, James Eagan Holmes, allegedly carried out the act with a number of handguns, as well as an AR-15 assault rifle with a 100-round drum magazine. Some lawmakers used the incident, which took place in a state with some of the laxest gun control laws, to bring forth legislation designed to place increased regulations on access to such weapons, but many observers, citing previous experience, were hesitant to say that they would be able to overcome the power of the National Rifle Association and Washington gun lobby.

Sikh Temple Shooting

On August 5, 2012, white supremacist Wade Michael Page opened fire on a Sikhs gathered at a temple in Oak Creek, Wis., killing six and wounding four more before turning the gun on himself.
