McConnell said it would be Democrats, who he charged were shoving aside the military and children by opposing the House bill, which includes a six-year extension of the children's health insurance program.
House Republicans passed the spending bill out of their chamber Thursday night, but the bill's future in the Senate is precarious with more than a dozen Democrats already having announced they'd vote against it.
Senate Majority Leader Mitch McConnell is urging his Republican colleagues against joining Democrats in opposing a bill preventing a federal shutdown.
The plans serve in part as a threat to Democrats, who have grown increasingly willing to keep McConnell from the 60 votes he would need to pass a short-term funding bill and avoid a shutdown.
The Republican leadership has little room for error with Democrats threatening to withhold their support from any bill that does not reinstate protections for people brought to the US illegally as minors, commonly referred to as "Dreamers".
Democrats, though, want the legislation to be paired with a fix to the Deferred Action for Childhood Arrivals (DACA) program, which is set to phase out in March. The White House later backtracked and said the president supported the spending bill. Within the Democratic party, some lawmakers up for re-election may not want to risk being blamed for a government shutdown. "That is not in anyone's interest", Ryan said.
The US Government could shut down for the first time since 2013 today, as the third temporary funding bill of the fiscal year expires.
Majority House Republican leaders, for their part, had to keep almost all of their members in line in order to approve the short-term spending legislation by a 230 to 197 margin. "There's nothing, nothing in such a continuing resolution that my Democratic friends actually oppose", he said.More news: Vladimir Putin takes icy plunge as Orthodox believers mark Epiphany

"I still believe we can keep the government open, solve the issues we've failed to address for several months and govern this country the way the American people expect us to, but the short-term bill that House Republicans passed tonight simply doesn't meet the test of basic governance".
It's a push that the White House and Republicans say they would back if it's coupled with tough border security measures and other restrictions.
So far, the votes needed to pass the bill in the Senate and avoid a shutdown just aren't there.
Rep. Mark Meadows, the Republican chairman of the House Freedom Caucus, says he's going to recommend to members of the group that they vote for a continuing resolution to keep the government running.
The bill has now made its way to the Senate Thursday evening, where Senate Democrats are, as of late Thursday afternoon, leaning towards shooting down the bill for not including DACA protections.
Republican congressional leaders have said DACA should be kept separate from government funding.
"I think some of our members would like to see us negotiate the bigger deal and do a short-term CR for a few days", Republican Senator John Thune said.
