Texas Sen. Ted Cruz ripped Joe Biden after he claimed that he would sacrifice hundreds of thousands of jobs to fight climate change.

During the PBS/Politico primary debate on Thursday, Biden, 77, said he would be willing to cut hundreds of thousands of jobs in the natural gas and oil industries to combat climate change.

"The answer is yes," Biden said. "We should, in fact, be making sure right now that every new building built is energy contained, that it doesn’t leak energy, that in fact, we should be providing tax credits for people to be able to make their homes turn to solar power. They’re all kinds of folks — right here in California, we're now on the verge of having batteries that are about the size of the top of this podium that you can store energy when, in fact, the wind isn’t blowing and the sun isn’t shining. We have enormous opportunities."

Cruz, 48, was disgusted by Biden’s answer. In a tweet, the senator trashed Biden for being willing to kill hundreds of thousands of American jobs in the natural gas industry while his son, Hunter Biden, raked in piles of money while working for the Ukrainian natural gas firm Burisma.

“Silly workers. They shouldn’t be concerned. Burisma is hiring,” Cruz wrote.

Burisma forked over $50,000 per month to Hunter Biden while his father was leading diplomatic efforts in the region while working under President Barack Obama. The younger Biden had no experience in the energy sector and had recently been cut by the Navy over his drug abuse issues , but Burisma added him to the company’s board.

Cruz has criticized the former vice president over his son’s position at Burisma, saying, “The reason Hunter Biden got that position is because his daddy was vice president of the United States.”
