Messaging war over Trump's 'big beautiful bill' heats up between Democrats, Republicans

"We welcome the debate, because this is the debate that's going to actually help us as a Democratic Party, build our coalition again and win elections," the DNC chair said in an exclusive interview with Fox News Digital.

That's just fine with Martin.

"If this is the ground they want to die on, the hill they want to die, we'll make sure they die on it," Martin said of Republicans.

"This is going to help every family in every community all across the country," Whatley predicted in his Fox News Digital interview.

But Martin disagreed, saying that "there is nothing in this bill that's going to help hard-working Americans. Let's be very clear, this is a giveaway to the richest people in our country."

The measure also provides billions for border security and codifies the president's controversial immigration crackdown.

The massive tax cuts and spending package is also projected by the Congressional Budget Office (CBO) to increase the national debt by $4 trillion over the next decade, but many Republicans dispute the projection.

And the new law also restructures Medicaid-the almost 60-year-old federal program that provides health coverage to roughly 71 million low-income Americans. The CBO this week estimated that 10 million people could lose their health insurance over the next decade.

"The fact is that we're going to be moving illegal aliens off of Medicaid. We're going to be strengthening the program," Whatlley said. "Those are things that absolutely need to happen."

"American people are hurting right now, and there's no doubt that this is an issue that allows the Democrats right now to actually rebuild our coalition, to actually bring people back in, many who left our party over the years, who felt like we weren't fighting for them and actually lifting up working people," Martin said.

And the DNC chair argued that "Donald Trump has betrayed them. I don't call this the big beautiful bill. What I call it is a big, ugly betrayal, because that's exactly what it is. It's a betrayal to the hardworking Americans who expected more from this president."
