Democrats have characterized the spending bill as a Democratic victory, but the American people really won, he said.
Another Florida Republican, Thomas Rooney, said confusion over the potential loss of coverage for pre-existing conditions had his constituents scared that "they're going to die because of a vote that we might be taking". Trump also asserted the bill allows insurance sales across states lines, something that's not in the bill at all.
The bill includes $21 billion in additional defense spending - $6 billion in the underlying bill and $15 billion added to the supplemental, Mulvaney explained.
"That's not all of the spending on border security".
"We have more money now for the border than we've gotten in 10 years", he said. Late in the day, the White House said Trump would indeed sign the bill. Asked to explain Trump's advocacy for a shutdown, Mulvaney said, "Right now I'm not anxious about September, I'm anxious about this deal that's in front of us".
The Financial Services Committee's effort got off to a slow start Tuesday as Democrats insisted that much of the 600-page replacement bill be read aloud before the committee considered amendments.
"Republicans have made Trumpcare even more risky and destructive than the last time they brought it to the floor", Democratic Leader Nancy Pelosi said to her caucus in a letter late Wednesday night.
"What didn't the Democrats get?" The Democrats didn't tell you that. Why are the Democrats saying that? The bill's supporters say it protects those with pre-existing conditions and that the exclusion would affect only some of them.
Democrats boasted of money for foreign assistance and cash-strapped Puerto Rico while winning funding for favored programs like transit projects and grants for first responders.
The GOP caution further underscores the difficulty that Republicans have had in making the transition to governing, after eight years in which they could unite in decrying Obamacare without having to craft legislation that might actually become law.
The money in Upton's plan would help people with pre-existing illnesses pay premiums in states where insurers can charge them more.
Complicating the Republicans' task is the apparently growing popularity of the law they want to replace, particularly in California. We wouldn't give it to them. "We should have brought full 100% repeal of Obamacare to the floor (the) first week in January, sent it to the Senate", he said.
Democrats also issued a last-minute demand for renewable energy subsidies for wind and solar, Mulvaney said, but they didn't get it. But the call was beset by technical troubles, and Mr. Mulvaney was able to offer few assurances to temper Mr. Trump's threat of a shutdown, which could leave Republican House and Senate candidates vulnerable in 2018 races if a shutdown occurred.
"They're walking around trying to make it look like they pulled one over fast on the President", he said.
"I think the president's tweet was that we might need a shutdown at some point to drive home that this place, that Washington needs to be fixed".
Missouri's U.S. Senator Roy Blunt, a fellow Republican, said he understood Trump's frustration with the Senate requirement for 60 votes to pass legislation, but cautioned against rushing to blow up the long standing rule. She said the new changes don't improve the bill and instead are "an assault on the good health of the American people".
But the move announced late Wednesday by GOP leaders also carries extreme political risk, as House Republicans prepare to endorse a bill that boots millions off the insurance rolls and may not even survive the Senate.
President Donald Trump tweeted Tuesday that the measure is the best bargain that can be had because its passage needs Democrats to meet the Senate's 60 vote threshold.
