Watch: Kennedy Stumps Biden Official on $50 Trillion Cost to Fight Climate Change: ‘You Don’t Know, Do You?’

Sen. John Kennedy, R-La., left one Biden administration official without words Wednesday when he pressed him to answer one simple question: How much would spending $50 trillion in American taxpayer money to become carbon-neutral lower global temperatures?

“If we spend $50 trillion to become carbon-neutral by 2050 in the United States of America, how much is that going to reduce world temperatures?” Kennedy asked Deputy Energy Secretary David Turk during a Senate Appropriations Subcommittee hearing.

Turk appeared unable to provide a specific number, and instead began arguing that the U.S. needed to do everything it could to reduce carbon emissions before being interrupted by Kennedy pressing for an answer to the question.
