House Speaker Mike Johnson lashed out at Democrats on Monday for creating the healthcare crisis they are now using to demand more than a trillion dollars in new spending to reopen the goverment, much of which would be used to continue subsidizing “Obamacare” medical premiums.

Democrats have kept the government shut down for more than five weeks by failing to side with Republicans on a clean continuing budget resolution to reopen the government. While most Democrats in the House opposed it, all the measure needed in the lower chamber was a majority vote, which it received thanks to GOP support.

But in the Senate, 60 votes are needed to overcome the filibuster and advance legislation. So far, only a few Democrats have joined the 53 Republicans to support the bill after Senate Minority Leader Chuck Schumer (D-N.Y.) instructed his caucus to oppose the bill and keep the government shuttered while demanding the Obamacare subsidies be added before they expire next month.

Republican leaders have said they are willing to negotiate the subsidies but demanded that Democrats support the clean spending bill to reopen the government after many of them supported an identical measure last spring.

At a Monday press conference, Johnson addressed the subsidies and blamed Democrats for using them as leverage to reopen the government.

“It is the Democrats who created Obamacare. It is the Democrats who did that without any Republican votes” during then-President Barack Obama’s first term, Johnson said.

“It’s the Democrats who by extension have cost the American taxpayers and people who have health insurance, have made their costs skyrocket,” he added.
