A lawmaker on Thursday asked the FBI to investigate the role conservative-favored social network Parler played in the storming of the U.S. Capitol early this month.
Rep. Carolyn Maloney, D-N.Y., who chairs the Committee on Oversight and Reform, sent a letter to the director of the FBI calling for it to look into Parler as well as ties it might have to Russia.
Maloney asked the investigation of the Jan. 6 attack include "robust" scrutiny of Parler, including "as a potential facilitator of planning and incitement related to the violence," according to a released statement.
Parler, which was forced offline by Amazon's web hosting division after the riot, could also hold evidence related to the attack, or of foreign governments financing civil unrest in the U.S., Maloney contended.
Some Parler users have been charged with threatening violence against elected officials or for taking part in the attack, according to Maloney.
She gave the example of a Texas man criminally charged for posting on Parler he would return to the U.S. Capitol and "hunt these cowards down like the traitors that each of them are."
Maloney said the oversight committee is conducting its own investigation and requested a meeting with FBI officials on the matter.
Apple suspended all downloads of the Parler app following the storming of the U.S. Capitol on Jan. 6, citing postings on the platform that could incite further violence. Google and Amazon also cut ties with the company.
Speaking to Fox News early this week, Cook justified suspending Parler, favored by supporters of former president Donald Trump.
"We looked at the incitement to violence that was on there, and we don't consider that free speech and incitement to violence has an intersection," Cook said.
Parler sued Amazon after Amazon Web Services cut off the platform's access to Internet servers.
Parler's popularity skyrocketed after Twitter permanently banned Trump following the Capitol attack, which has been condemned as an attack on US democracy.
Parler, which launched in 2018, operates much like Twitter, with profiles to follow and "parleys" instead of tweets.
In its early days, the platform attracted a crowd of ultraconservative and even extreme-right users. But more recently, it has signed up many more traditional Republican voices.
