Five liberal senators are demanding video sharing platform, YouTube immediately remove videos about gun making, blaming them for so-called “ghost gun” shootings. In a letter to YouTube’s CEO, Susan Wojcicki, the senators said that the platform has not been doing enough to remove videos about ghost guns.

The Washington Examiner reports:

The five, led by ardent gun-control advocate Sen. Richard Blumenthal, wrote without evidence that “ghost guns have become the weapon of choice for gun traffickers and convicted felons as well as domestic violent extremists and foreign terrorists. Federal, state, and local law enforcement officials have sounded the alarm that these untraceable firearms present a distinct and deadly threat and have exacerbated the scourge and surge of gun violence that has ravaged communities all across the United States.”

The legal firearms have been cited by police as a tiny slice of the guns used in crimes, though they have been seized on by anti-gun politicians as a symbol of gun violence.

They are not classified by the government as firearms because they are not fully functioning guns when sold in kits, and thus, do not require any serial number, which can be traced. Kits can be purchased online and at gun shows and require some construction to turn into working firearms. At last week’s NRA-sponsored Great American Outdoors Show in Harrisburg, Pennsylvania, there were at least two booths offering the “80% gun” kits, but there were few buyers when Secrets was observing.

Gun advocates have taken to YouTube to warn that the letter threatens their Second Amendment rights

The senators have made it clear they won’t stop until YouTube addresses the videos.

“Until YouTube devotes the time and resources necessary to actually enforce its Community Guidelines, the claim that safety is your highest priority rings hollow. YouTube can — and must — do more to ensure that the content it hosts does not exacerbate the threat of ghost guns,” wrote the five.
