Sen. Ron Johnson, R-Wis., said on Sunday he's disappointed by the amount of spending reductions in the House-passed "One Big Beautiful Bill Act."

The bill passed on Thursday with votes from all but two Republicans.

"One of my disappointments with what the House process is about, the only number we ever heard about was $1.5 trillion, which sounds like a lot, but it's only $150 billion per year," he said on CNN's "State of the Union."

"In 2019, we spent $4.4 trillion; this year we'll spend over $7 trillion, you know, $150 billion on that is basically a rounding error," he added.

Johnson said the Senate version of the bill should go further than the House on spending cuts to reduce the deficit. Johnson argued that Congress should have returned to pre-pandemic levels of spending when the trillions of dollars of economic stimulus programs ended.

He said the House-passed megabill would add more than $3 trillion to the deficit over the next 10 years. 

"Listen, this is the weekend we honor the service and sacrifice of the finest among us. You know, more than a million that died defend this nation. I don't think they served in sacrifice to leave our children completely mortgaged their future and their prospects diminished," he said.

Meanwhile, House Speaker Mike Johnson is encouraging the GOP-led Senate to keep the legislation largely untouched. 

"I have a very delicate balance here, very delicate equilibrium that we’ve reached over a long period of time. And it’s best not to meddle with it too much," the speaker said on Sunday.
