CNN anchor Jim Acosta has again drawn attention for calling out Fox News and Republicans. On Saturday, Acosta attacked Tucker Carlson for the conservative pundit's most recent unsubstantiated claims.

Acosta described Carlson as a “human manure spreader” for stating that Afghan refugees are being brought to the U.S. to influence future elections. Carlson claims that they will come here to vote Democratic.

Carlson made the comments Tuesday on the Fox News program "Tucker Carlson Tonight." Carlson pegged his conspiracy theory, “Operation Change America Forever.” 

“Over on Fox, 'human manure spreader' Tucker Carlson has floated yet another race-baiting conspiracy theory that tens of thousands of Afghan refugees are being welcomed into this country in order to change the outcome of future elections,” Acosta said.

Acosta had also shown a clip of Rep. Louie Gohmert, R-Texas, who had said he had been told that, “there is a significant percentage [of Afghan refugees] that are future Boston marathon bombers because they’re not doing the adequate vetting.”

Carlson had suggested that the Afghans are invading the U.S.

 “First we invade, and then we’re invaded,” said Carlson. He warned that the refugees are “probably” coming to live in “your neighborhood.”

Acosta pointed to that conservatives have raised hysteria over refugees entering the country. The Pentagon and the Department of Homeland Security on Wednesday reported that 24,000 Afghan refugees have arrived in the U.S. since Aug. 17. Nearly the same number are at U.S. military bases in Europe and Asia.

“Leading figures on the far right have been sounding the alarm on Afghanistan evacuees all week,” Acosta said. "'The refugees are coming! The refugees are coming!'"

Acosta referred to Carlson, along with Republican Reps. Marjorie Taylor Greene of Georgia and Madison Cawthorn of North Carolina, as the “American Taliban.”

Twitter reacted to Acosta's comments.
