Watch: Obamacare architect tries to blame law's failures on Trump — then Chris Wallace steps in

Professor Jonathan Gruber, who is the chief architect of Obamacare, attempted to blame the law's failures on President Donald Trump on Sunday.

During a segment on "Fox News Sunday" where host Chris Wallace noted the recent Obamacare premium hikes and the fact that health insurance companies are dropping from the marketplace, Gruber tried to pin Obamacare's failures on Trump.

Noting that in Iowa all but five counties have only one insurance company — Medica, who said recently they are considering leaving the Iowan marketplace completely — Wallace said that Iowans, like many Americans, are facing a severe shortage of health insurance options thanks to Obamacare.

But according to Gruber, Trump is the man to blame.

"Look, and whose fault is this?" Gruber asked. "Before President Trump was elected, there were no counties in America that did not have an insurer."

Gruber tried to bury his outrageous claim by moving on, but Wallace wasn't having it.

"Wait, wait, wait, wait," Wallace interrupted. "Wait, you're going to blame the problems with Obamacare on President Trump?"

Indeed, Gruber was. He said that Obamacare was working fine before Trump "undercut" the Obamacare enrollment and renegaded on the "obligations [Obamacare] makes to the insurers."

"And as a result, premiums are going up and insurers are exiting," Gruber said.

However, that isn't exactly the truth. Health care premiums under Obamacare have been going up for years. To make matters worse, and to make health insurance even more unaffordable, plans today come with insane deductibles, making many plans useless.

But it was announced last October that Obamacare premiums would skyrocket an average of 24 percent in 2017, while some states, like Arizona, saw increases up to 116 percent — long before Trump was in the White House or even elected president.

Gruber wasn't able to make many more accusations before Wallace had to move the segment along.

Still, during the rest of the 11-minute segment, Gruber further blamed Obamacare's collapse on Trump, saying that Trump's election last November caused "massive uncertainty" in the marketplace, causing premiums to go up and insurers to exit the marketplace.

He also claimed that before Trump, health insurance companies were making a profit and happy with Obamacare. This, however, is demonstrably false.
