Sen. Chuck Grassley (R-IA) blasted Senate Democrats for holding over 10 hearings on climate change instead of discussing the United States's rising debt.

Grassley spoke during a Senate Budget Committee hearing on Tuesday called "Beyond the Breaking Point: The Fiscal Consequences of Climate Change on Infrastructure," blasting the committee and the Biden administration for the national debt.

"Our nation is over 32 trillion dollars in debt, yet this committee is holding the 11th hearing on climate change," Grassley said. "President Biden is on television bragging about his economic performance when Americans can’t afford groceries and gasoline. Our spending is out of control, and Democrats haven’t written a budget in the past two years."

Grassley added that climate change is a "topic very worthy of discussion," citing his authoring of the wind energy tax credit. Iowa reached a milestone last week, with the state recording 64% of Iowa's energy production coming from wind — a new record for the state and a record among states for the country.

"I fought for renewable energy long before climate change became such a politically popular topic," Grassley said. "Democrats called this hearing to discuss the fiscal impact of climate change on infrastructure. I imagine we’ll hear some expensive estimates and alarming anecdotes about the impact of severe weather events on infrastructure."

"But, there isn’t a single expert in this room who is qualified as a climate scientist to attribute those estimates and anecdotes explicitly to climate change," he continued.

Grassley has gone head to head with the Biden administration over the months. He voted in favor of a resolution to revise the "Waters of the U.S." rule in the Clean Water Act, which defines which waterways are subjected to federal pollution regulations. President Joe Biden later vetoed the resolution after it passed both chambers of Congress.

In May, the Supreme Court dealt a blow to the Environmental Protection Agency and the Biden administration in Sackett v. EPA. The ruling scaled back federal authority to regulate the Waters of the U.S. — a win for landowners and business groups who said the federal government was overregulating small bodies of water like wetlands.

Grassley praised the Supreme Court's decision as a "victory for farmers, builders, landowners, and common sense."
