Senator Ted Cruz (R-Texas) introduced an amendment on Wednesday that would cut off all funds for Obamacare, a step he said Republicans should support and, if it were to pass in the House as well, could be sent to President Barack Obama to see if he’s “willing to try to shut the government down” over funding of the Affordable Care Act.

“I think it’s the right position for Republicans to be taking,” Cruz told “And I think it would be exactly the right decision to then send it back to Harry Reid and President Obama and ask if Harry Reid and President Obama are willing to try to shut the government down in order to insist that Obamacare be fully funded now, even though it could well push us into a recession.”

“I think that is an important stand for principle that makes a difference in the lives of those who are struggling the most,” said the senator.

On Wednesday, Cruz introduced his de-fund Obamacare amendment to the continuing resolution (CR), which is a massive “must-pass” bill to keep the government funded for the rest of this fiscal year, from late March through the end of September.

Last week, the Republican-controlled House passed a $982-billion CR, but the GOP leadership set the rule and did not allow the must-pass CR to include language prohibiting funding for Obamacare or for de-funding the controversial Obamacare mandate that requires nearly all health plans to offer contraceptives, sterilization, and abortion-inducing drugs without co-payments.
