Fox News’ Tucker Carlson took a progressive radio host to task on Friday for Democratic hypocrisy on rising gas prices.

WATCH:

The Daily Caller co-founder started the segment by noting that Democrats have been calling for higher gas prices for decades because they think it will “somehow help fight global warming.” However, now that gas prices are higher under President Donald Trump, Carlson explained that Democrats now oppose the idea.

Progressive radio host Chris Hahn argued, “Trump should be attacking himself…he said [in 2011] blame the party in power for high gas prices.”

“I think that’s fair,” Carlson conceded, “but that doesn’t change the fact that Democrats as of last week…are calling for gas tax increases. They’re for a higher gas tax — it’s in the Democratic platform.”

“What kind of sick person do you have to be to attack someone for what you’re calling for?” Carlson asked incredulously.

Hahn retorted that Democrats are calling for a “useful” tax that will go to “other projects” rather than Trump’s policies, which Carlson again noted that Democrats have previously supported.

“He’s doing what Democrats have called on the country to do and it’s having an effect they agree with,” Carlson asserted. “It’s all so dishonest. It’s mind-blowing.”
