Bipartisan congressional leadership met with President Trump at the White House on Monday afternoon in a last-minute effort to avert the crisis. The meeting ended without an agreement.

Top congressional leaders are heading to the White House Monday afternoon to meet with President Donald Trump in a last-ditch effort to avert a government shutdown -- but as a stalemate persists just one day from the deadline, a shutdown seems nearly inevitable barring an unexpected breakthrough.

The possibility of a shutdown raises questions about what it would mean for lawmakers themselves — and their paychecks.

Trump’s sit-down on Monday with Jeffries, Schumer, House Speaker Mike Johnson (R-La.) and Senate Majority Leader John Thune (R-S.D.) was his first since becoming president in January. He canceled a meeting with Democrats last week, declaring that no meeting could possibly be productive.

Democrats face criticism for planning a luxury Napa Valley retreat while Congress works to avoid a government shutdown before the end of September.

While some federal contracts will stop work in the event of a shutdown, others will continue on, particularly if they’re funded by appropriations from past fiscal years. PSC officials explained, however, that problems emerge when contractors need an action by or information from a federal employee who is furloughed.

Social Security is considered mandatory, and funding for those programs is generally unaffected by a shutdown. Medicare benefits also continue uninterrupted. The federal government has enough money for Medicaid to fund the first quarter of the next fiscal year, according to the Centers for Medicare and Medicaid Services.

House Speaker Mike Johnson, R-La., and House GOP leaders urged their fellow Republicans to stay united ahead of a likely government shutdown during a lawmaker-only phone call on Monday, Fox News Digital has learned.

The 2018-19 shutdown — which lasted 35 days, making it the longest in history — was also the second to occur during Trump’s first presidency. That shutdown ended after East Coast airports faced major delays when unpaid air traffic controllers stopped coming to work.

A prolonged government shutdown, as occurred in 2018, could lead to long lines at TSA checkpoints and economic losses, experts warn.
