"Are you going to believe what he tells you at 11:30 this morning?" Trey Gowdy (R-S.C.) asked during a Thursday morning interview on Fox News.
"Twenty-seven different times he told you, you and I would never be having this conversation, because if you liked your insurance you could keep it. And for those who weren't paying attention, he said 'period.'"
The president is expected to say that Americans can keep their insurance policies even if they don't meet Obamacare coverage requirements. He would administratively "grandfather" more individual plans.
Gowdy said Obama is seeking a "political remedy" -- "because his dream of retaking the House has now turned into the nightmare of, he may lose the Senate -- because half of the people that he works for don't believe what comes out of his mouth."
Gowdy said President Obama is making his announcement on Thursday to prevent Democrats from joining House Republicans on Friday in voting for Rep. Fred Upton's (R-Mich.) "Keep Your Plan" bill.
"This is not a legislative fix," Gowdy said. "If it were a legislative fix, he would be working with Fred Upton and the House Republicans to pass the bill on Friday. This is all about politics. He doesn't want Republican to ride in on a white horse and save this abysmal ruling of Obamacare, so he wants to do something administratively or through executive order.
"I just hope my fellow citizens are savvy enough to say, 'Why should we believe you now?'"
Upton's bill would allow people to keep the insurance policies they had in 2013 for another year, without penalty, even if those plans do not meet Obamacare coverage requirements, and it would let insurance companies keep selling those policies for another year. Democrats say the Upton bill would gut Obamacare, which is based on people going into the new exchanges.
House Democratic Leader Nancy Pelosi said Thursday morning that she would prefer an administrative fix, "because that could be done much more quickly without any accompanying agendas."
