Texas Gov. Greg Abbott is one person who has called into question a multi-state, eight-week training exercise that involves several branches of the U.S. military. The training exercise is called Operation Jade Helm, and it is set to take place in July and August.

But on Sunday, Texas uber-conservative, actor and martial arts expert Chuck Norris joined him with an op-ed he did on the conservative website World Net Daily.

"Concerned Texans and Americans are in no way calling into question our brave and courageous men and women in uniform. They are merely following orders," Norris said in the article.

"What's under question are those who are pulling the strings at the top of Jade Helm 15 back in Washington. The U.S. government says, 'It's just a training exercise.' But I'm not sure the term 'just' has any reference to reality when the government uses it."

Norris also cited an ISIS threat, which he believes is stemming from Washington.

"Whatever Jade Helm 15 actually is, I think it is more than coincidental that the FBI director just confessed in February that the presence of ISIS can be felt in all 50 states of the U.S. and that the Pentagon is suddenly running its biggest military training exercise with every branch of the military across seven Southwestern states," Norris wrote.

"Whether deterrence, display of power or something more covert or devious, let's not come with any patronizing nonsense of impotence and simplicity when its origin is in Washington."

According to The Washington Post, the training exercise has designated Texas as "hostile" territory for purposes of the simulation. This has fueled the ire of Texas conservatives, especially on the federal political level with Sen. Ted Cruz, who spoke with Bloomberg.

"We are assured it is a military training exercise," Cruz said. "I have no reason to doubt those assurances, but I understand the reason for concern and uncertainty, because when the federal government has not demonstrated itself to be trustworthy in this administration, the natural consequence is that many citizens don't trust what it is saying."
