WASHINGTON, D.C. - U.S. Rep. Tom Reed is taking on Twitter.

During a news conference this morning in Washington, Reed, a Corning Republican, and members of his bipartisan Problem Solvers Caucus called on the social media giant to ban content from foreign terror groups like Hamas and Hezbollah.

In September, Twitter told Congress it would restrict that content. However, the company later allowed for exceptions that would permit those groups to use the site, according to the lawmakers.

Hamas and Hezbollah are designated as Foreign Terrorist Organizations by the U.S. State Department, which makes it illegal for Americans to aid those groups in any way.

Lawmakers have given twitter until November 1 to comply.

“If Twitter is supporting a terrorist organization such as Hamas and Hezbollah, every American out there should say hell no are we going to participate with such an organization such as Twitter,” Reed said during Tuesday’s news conference.
