Kentucky Republican Sen. Rand Paul called out his fellow Republican South Carolina Sen. Lindsey Graham over Ukraine aid Thursday while on Fox Business.

Graham told reporters Wednesday those opposed to giving Ukraine more aid should stay out of it until they’ve visited Ukraine and seen the war firsthand.

“Somebody needs to remind the Senator that we don’t have any money. We are about $1.5 trillion dollars in debt for this year. Over the last three months we’ve accumulated almost a trillion dollars in three months. The total is $33 trillion, so we don’t have like an extra rainy day fund or a surplus we can send them,” Paul said in response.

“We have to borrow the money from China to send to Ukraine, so no matter what your sympathies are in the war, and I am sympathetic to Ukraine fighting off the Russian aggressors, but at the same time I think it’s irresponsible to think about their country before I think about my country.”

Paul claimed U.S. funding is also helping Ukrainian government worker pensions, and he believes most Americans agree with him that aid needs to be cut.

Paul then went on to criticize Ukrainian President Volodymr Zelenskyy for saying he’s not holding elections next year, claiming it would be inconvenient during a war and expensive. Paul then argued Europe has a greater incentive to help Ukraine fight off Russia, and Ukraine should rely on its neighbors.

Zelenskyy is visiting the White House and Capitol Hill this week to ask the U.S. for more aid in addition to the $100 billion that Congress has already approved, per The Wall Street Journal. President Joe Biden’s administration has called for an additional $24 billion in aid amid a spending conflict that threatens a government shutdown Sept. 30.

Other Republicans have expressed opposition to additional funding.

“There’s no money in the House right now for Ukraine,” Florida Rep. Byron Donalds told The Recount. “It’s not a good time for [Zelenskyy] to be here, quite frankly. That’s just the reality.”

Republican Arizona Rep. Paul Gosar told the Daily Caller News Foundation he would never support additional funding for Ukraine, since there are more dire issues domestically.
