Senate begins debate on Trump's 'big, beautiful bill'

Asked if he is open to temporarily pulling away from his personal crypto ventures as a bill that aims to regulate cryptocurrencies faces some criticism due to conflict-of-interest concerns raised by the president's dealings in stablecoins, Trump said he is a "fan of crypto" and called it a "very powerful industry" that the U.S. has "dominated."

"I'm president. And what I did do there is build an industry that's very important," he said. "If we didn't have it, China would."

In recent years, China's government has imposed stringent restrictions on trading crypto.

House Speaker Mike Johnson suggested the self-imposed July Fourth deadline to pass the One Big Beautiful Bill Act could slide.

"It's possible," he said. "I don't even accept that as an option right now."

Johnson said the House can't make any final decisions until the bill passes in the Senate and hopes the final product is like what the House passed.

"I'm going to give all of my members plenty of time to digest that we're not -- the House will not be jammed by anything," he said.

The speaker said he'll bring the House back next week to "get this done as soon as it is possible."

"So, I still want to get this done by July Fourth," he said.

When Trump was asked if his July Fourth deadline for his megabill were important, he appeared not to be committed to the date.

"It's important, it's not the end all," he said. "It can go longer, but we'd like to get it done by that time if possible."

When asked on the state of his megabill, a day after the Senate parliamentarian rejected a key Medicaid provision, Trump claimed that the Democrats don't want to approve the bill "because politically, it's so good for the Republicans."

"But think of what they're not approving. They're not approving border security," he said, going on to add, "If I were a Democrat, I would vote for this bill."

Surmising on who among the Democrats might vote for it, he said he thought Pennsylvania Sen. John Fetterman would "because he seems to be the most sensible one lately."
