3:00 PM PT -- We got Jesse as he walked out of the courthouse, surrounded by his Mongol MC "brothers," and he made it clear he never tried to hide his membership in the organization ... even when he was in politics. As he put it, "I don't run from being a Mongol."
1:15 PM PT -- Prosecutors asked Jesse about the Mongols MC allegedly retaliating for the killings of members ... and he said he'd lose respect for them if they didn't. During cross-examination, he conceded every organization has "some bad apples."
On a lighter note, Jesse referred to himself as a "gringo biker" who was never harassed while riding around East L.A. -- noting Mongols membership is about 75% Latino and 25% white.
He's now completed his testimony.
Jesse Ventura has found himself smack-dab in the middle of a real-life "Sons of Anarchy" storyline ... as the feds try to nail a biker gang on racketeering and conspiracy charges.
The legendary pro wrestler and former Minnesota Governor appeared in an Orange County courtroom Wednesday to testify on behalf of the Southern California-based Mongols Motorcycle Club ... of which he's an inactive member.
He was called as an expert witness for gang members who were accused of murder, drug running, robbery, extortion and other crimes. Jesse said under oath when he was a member of the MC he never engaged in criminal activity. He testified he was never asked to commit crimes and never did.
Jesse went on to praise the MC. He stated that joining the Mongols in the '70s helped him transition from the military -- where he was a Navy Seal -- to civilian life, and gave him a "brotherhood to rely on."
Ventura worked his way up to a Sergeant-at-Arms during his short time in the club, before leaving in 1974 to pursue his wrestling career.
It's interesting timing ... we just spoke with Jesse Tuesday, and he told us he's seriously thinking about running for President in 2020 against Trump.
We would say his affiliation with this case might hurt his chances, but controversy and legal trouble didn't deter Trump, so ... let the race begin?
