WATCH: Obama calls Benghazi attack a 'wild conspiracy theory.' Benghazi hero decimates him.

Former President Barack Obama was in mid-season form on Friday when he launched a broadside against President Donald Trump and congressional Republicans at the University of Illinois-Urbana Champaign.

One attack in particular earned the scorn of Kris Paronto, one of the heroes of Benghazi.

What did Obama say?

Obama suggested that outrage over the 2012 attack on the U.S. consulate in Benghazi — which resulted in the deaths of four Americans, including U.S. Ambassador Christopher Stevens — was the result of Republican "conspiracy theories."

"But over the past few decades, the politics of division and resentment and paranoia has unfortunately found a home in the Republican party," Obama said.

The former president accused the Republican-controlled Congress of "unwinding campaign finance laws," "systematically [attacking] voter rights," implementing tax cuts "without regard to deficits," "slashing the safety net," and casting votes to "take away health insurance from ordinary Americans."

Obama then charged that Republicans in Congress have "embraced wild conspiracy theories, like those surrounding Benghazi."

In actuality, Republicans in Congress, though they pursued the truth behind the attack with tenacity, did not push conspiracy theories during the Benghazi investigations. It was the Obama administration that blamed the attack on a YouTube video, which was later proved categorically false.

How did Paronto respond?

The former U.S. Army Ranger — who worked as a CIA security contractor to protect the CIA's Benghazi annex saving countless lives during the coordinated terrorist attack — had strong words for Obama.

Benghazi is a conspiracy @BarackObama ?! How bout we do this,let’s put your cowardly ass on the top of a roof with 6 of your buddies&shoot rpg’s&Ak47’s at you while terrorists lob 81mm mortars killing 2 of your buddies all while waiting for US support that you never sent🖕🏼#scum
