WATCH: Expert terrorism witness invited by House Democrats once called for suicide bombing of Trump Tower

The House Subcommittee on Crime, Terrorism, and Homeland Security held the hearing Wednesday to examine the "Rise of Domestic Terrorism in America."

During his testimony, Ngo urged lawmakers to treat far-left violent extremism with greater severity. He was rebuffed by House Democrats who continue to point at white supremacy in the aftermath of the Capitol Hill riot on Jan. 6.

"It's my understanding of the law that these do count as terrorist acts, but they’re not being reported as such or perceived as such for political reasons," Ngo said, criticizing the mainstream media and citing examples of how Antifa groups were involved in organized crime that resulted in deaths, arson attacks, and vandalism.

MSNBC terrorism analyst Malcolm Nance was the star witness called on by House Democrats to testify and appear opposite Ngo.

"He kept downplaying all the points I was making about Antifa's violent extremism, in fact comparing it to unruly Super Bowl revelers," Ngo told Ingraham. "I found those comparisons quite sick." Ngo emphasized that Antifa's organized violence has led to the assaults and deaths of numerous Americans.

Ngo himself was attacked in downtown Portland when Antifa radicals left him hospitalized with severe injuries back in 2019.

In his written statement, Nance argued that most Domestic Violent Extremists (DVEs) "seek to protect and defend rights not as they are written in the Constitution, but as they wish they had been written." He went on to name subclasses, including Christian identity movement groups, anti-tax extremists, anti-abortionist extremists, and anti-immigrant macro-nationalists.

Nance contended that the election of former President Donald Trump gave the aforementioned movements "a tribal chieftain" to rally behind. Ingraham commented that Nance appeared to group any individual affiliated with pro-life and pro-border enforcement associations as part of an anti-government mob that must be surveilled.

Ngo expressed that he is "disturbed" and "scared" about American public safety if Washington officials are "getting advice from so-called professionals and experts who view the burning of buildings that are occupied by people [and] the use of firebombs and homemade explosives as merely civil disobedience."

Following Trump's call to Turkish President Recep Tayyip Erdogan for winning the 2017 referendum, Nance had "nominated" Trump Towers Istanbul, two conjoined towers in Turkey that are part-office space and part-residential, to be suicide bombed by terrorist organization Islamic State of Iraq and Syria (ISIS). Nance was responding to writer Dustin Giebel's tweet suggesting that Trump's congratulatory call regarding the controversial victory was motivated by reasons tied to the estate.

"This is my nominee for first ISIS suicide bombing of a Trump property," Nance wrote in his since-deleted 2017 tweet, The Federalist reported. Nance has accused Trump of promoting ISIS through his actions and words, calling the Republican leader on the 2016 campaign trail "the ISIS candidate" who "inflames the passions of people in the West to perform Islamophobia" and "to draw recruits to them."

Conspiracy-crazed, Nance became one the most vocal pundits perpetuating the never-ending Russia hoax to smear Trump, along with any and all political adversaries, as Kremlin assets. In August 2016, the MSNBC contributor flat-out lied on television, claiming that Green Party presidential candidate Jill Stein has her own show on Russia Today. MSNBC anchor Joy Reid failed to correct Nance.

Two years later in 2018, independent journalist Glenn Greenwald pointed out in The Intercept that the network still refused to ever offer any correction, allowing MSNBC viewers to believe that Stein hosted her own program on the state-controlled outlet funded by the Russian government's federal tax budget.

Then in an interview with the New Yorker in 2019, Nance took aim at Greenwald. He alleged on Twitter that The Intercept's co-founder "shows his true colors as an agent of Trump and Moscow." The expose occurred even after the release of the Mueller report that debunked the four-year Russia conspiracy.

"He's deep in the Kremlin pocket," Nance tweeted of Greenwald, claiming that he "reports into his masters in Moscow to help set the record straight about how misunderstood Russia is (when not sucking up to Trump on Fox)."

Greenwald fired back that "[n]one of Nance's statements here is opinion," but are "intended to be factual." He wrote, "They are all outright lies. There is no other way to describe them." Nance boasted how proud he was to have broadcasted those falsehoods, "because Nance knows that he is free to lie this way with impunity," Greenwald volleyed. When pressed on his disproven allegations that contradict what was outlined in the Mueller report just several months prior, Nance responded, "That's why it is called analysis." He went on to cite several books written on the topic refuted by special counsel investigation.

A former naval intelligence officer, Nance is accused by his peers of exaggerating his military accomplishments while in the service, according to Desert Storm veteran Peter Morlock for Special Operations Forces Report (SOFREP).

Morlock claimed that Nance "left the Naval Security Group in disgrace" and now the professional communities and associations "laugh at his self-promotion, exaggeration of performance and associations, and his pretense of expertise."

"The proverbial 'eye roll' precedes any response we give when asked about his exploits," Morlock penned, noting that Nance has been declared persona non grata (PNG) from his profession and then "presumes to question" the honor of service members based on their conservative views. The accusation came after Nance that all military personnel who support Trump are "not honorable."
