Fox News host Tucker Carlson has ignited multiple waves of controversy in recent years with contentious comments about journalists, immigrants, and women.

Since receiving his own show on Fox News in 2016, Carlson has had several controversies play out in front of one of the country's largest audiences.

In August, he claimed white supremacy was "actually not a real problem in America."

His most recent controversial comment is that House Intelligence Committee Chairman Adam Schiff is mentally ill.

Fox News host Tucker Carlson is no stranger to controversy.

In August, three days after a mass shooting in El Paso, Texas, where the shooter wrote a manifesto about a "Hispanic invasion of Texas," he told his near 3 million viewers that white supremacy was "not a real problem."

"It's a conspiracy theory used to divide the country and keep a hold on power," he said.

On September 26, Carlson struck again. This time his target was House Intelligence Committee Chairman Adam Schiff, whom he said, without evidence, was mentally ill.

Since getting his own show on the network in 2016 — which would eventually move into former Fox News host Bill O'Reilly's prime time slot — Carlson's on-air comments about journalists, immigrants, and women have landed him in hot water.

Since late 2018, dozens of companies have stopped airing advertisements during his show.
