Asked specifically about a clean hike, Ryan said there are "a bunch of different options in front of us".
Trump's recent actions - hitting Ryan, McConnell and GOP senators and threatening a government shutdown over funding for his proposed border wall - potentially complicate the Republican agenda when lawmakers return to Washington.
Ryan said GOP leaders "were looking at" that option but decided against it. Ryan's comments echoed Senate Majority Leader Mitch McConnell , who on Monday said "there is zero chance" that the USA will fail to raise the debt ceiling .
Ryan focused on tax reform in his address of Intel employees and said he was impressed by the work Intel does. "We made a promise, we ran on this, we said this is necessary, this is what we're gonna do". "We think a short-term spending bill (aka continuing resolution or CR) to keep the government open will pass but any CR will kick the can down the road until near the end of the calendar year and that is when, in our view, the prospects for a government shutdown become more likely".
"The fact is though, given the time of year it is and the rest of the appropriations we have to do, we're going to need more time to complete our appropriations process particularly in the Senate - so that's something that I think we all recognize and understand", Ryan said.
The S&P 500 Index and Dow Jones Industrial Index both fell Wednesday following Trump's threats, while gold futures rose.
Still, the analysts put the odds of a government shutdown at the beginning of October at less than 50 percent - but December is another story. Trump is making noise about not raising the debt ceiling, a routine matter wherein Congress allows the Treasury to issue debt to allow the country to pay its bills.
Aides have said Republicans aren't close to coalescing around a Republican-only debt ceiling bill.
If the two are attached, Trump's veto threat becomes more significant, risking a partial shutdown October 1 and a debt payments default shortly thereafter.
