(CNN) - Sen. Ron Johnson, R-Wisconsin, blasted President Barack Obama's now infamous "keep your healthcare" pledge on Saturday in the GOP's weekly address.
"Millions of Americans are coming to realize that those are your tire tracks on their cancelled policies," Johnson said about the President, arguing that it's "obvious that you didn't inadvertently misspeak when you promised Americans they can keep their doctors and health plans."
Johnson attacked Obama's pledge as not an inadvertent mistake but "statements that were fully vetted, coldly calculated, and carefully crafted to deceptively sell your health care plan to a trusting public," he said.
The pledge, Johnson said, amounts to a "political fraud," one perpetuated by congressional Democrats.
"Consumer fraud this massive in the private sector could – and should – bear serious legal ramifications," Johnson said.
"For President Obama, however, it helped secure enough votes to pass Obamacare, and win reelection."
On Thursday, Obama issued an administrative fix aimed at easing concerns of millions of Americans on the individual market whose policies have been cancelled because they didn't meet the minimum standards of coverage under the health care law.
House Republicans say the fix is not enough.
On Friday, the House passed a Republican bill that would authorize plan extensions and allow others to sign up for them as well – although the measure has little chance with the Democrat-controlled Senate and White House.
They believe the measure goes too far and that Obama has already taken care of the problem.
"Unfortunately, the implementation of Obamacare has progressed to a point where millions of cancelled plans cannot be reinstated," Johnson said of the attempted fixes.
"But the freedom of millions of Americans to keep doctors, treatments, and health plans they do value can still be preserved if Congress acts swiftly and decisively."
What the problems plaguing Obamacare amount to for Johnson and other Republicans is a full magazine of ammunition to attack Democrats in the 2014 midterms and beyond.
"Hopefully, Americans who were deceived will question the credibility of those who made so many false promises," Johnson said.
