Trump called for the so-called "nuclear option" but also said the party could strengthen its hand by winning more Senate seats in the 2018 congressional election.
The path was discernible in a almost $1.2 trillion federal spending deal carved out over the weekend to avert a government shutdown. Although bipartisan support is predicted, some House conservatives aren't necessarily on board.
Talks on the spending bill were spurred by the need for Democratic votes to pass spending bills.
And that cuts both ways - in the same poll, 69% said Democrats ought to be trying to compromise with Trump and not just resist the president's agenda.
Lawmakers managed to avoid a government shutdown last week and over the weekend, first passing a stopgap, one-week funding bill and then agreeing on a deal to fund the government through September 30, the end of the fiscal year.
"Mulvaney cited a $15 billion infusion of defense spending '" about half of what Trump asked for in March '" as a huge win.
Trump and the White House had made concessions last week when the president relented on his demand that the measure include a $1.4 billion down payment for his proposed wall along the U.S. -Mexico border.
Republicans have promised for years that, if they had control of the government, they'd defund Planned Parenthood.
The new agreement follows a stretch of deal-making on Capitol Hill that led the Trump administration to concede on two sticking points.
Top House Democrat Nancy Pelosi branded the deal "a defeat for President Trump".
Democrats took an opposite view.
"Either elect more Republican Senators in 2018 or change the rules now to 51%", Trump tweeted in reference to Senate rules requiring 60 votes to end a filibuster.
"We have boosted resources for our defense needs without corresponding increases in non-defense spending", Ryan said in a statement.
Democrats had leverage in the talks because their votes will be needed to pass the bill. There will be more pressure on Trump to see his priorities come through in next year's spending plan.
U.S. congressional leaders on Monday unveiled a bipartisan deal funding government through September, with a compromise that includes President Donald Trump's call for increased military spending but ignores his demand to fund a border wall. Democrats were pushing to have those payments included in the spending bill, but the White House promise to keep the payments going, at least for a short while, was enough to bring them along.
Congress will send Trump a revised Fiscal Year 2017 budget on Monday that represents small shifts in his direction, but Democrats stymied numerous White House's priorities - and will likely do so again when battles begin anew over the 2018 budget later this month.
"The president said what?"
The deal reportedly increases defence spending by $25bn and $1.5bn for border security. He also wanted to immediately eliminate the Great Lakes Restoration Initiative, Community Development Block Grants and the "TIGER" transportation grants that have been funding the return of cars to Buffalo's Main Street.
There's $2 billion in new spending for the National Institutes of Health.
Instead, congressional negotiators settled on $1.5 billion more for border security, including more money for new technology and repairing existing infrastructure, the aide said.
Under the deal, Puerto Rico would get an emergency injection of $295 million for its Medicaid health insurance program for the poor.
Extra dollars in the spending deal would help fund the US wars in Afghanistan, Iraq and Syria, as well as replenish equipment and pay for training and maintenance.
