Obamacare architect Jonathan Gruber was called out Sunday for blaming the health care law's failures on President Donald Trump.

"Fox News Sunday" host Chris Wallace stopped Gruber after he began blaming Trump for insurance companies pulling out of Obamacare exchanges.

Wallace pointed out that in most of Iowa, there is only one insurer participating in the state's exchange, noting that it is considering leaving as well.

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

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

Gruber tried to defend his comments, arguing that many insurance companies wanted to be in the markets and companies made money. Several insurance companies were leaving before Trump was sworn into office in January, however.

Gruber was one of the main individuals who helped the Obama administration and Democrats in Congress create the Affordable Care Act.
