A Democratic congressman from New Jersey is leading the charge to double the punishment for convicted insurrectionists in the wake of the Capitol Hill riots.

“What happened on Jan. 6 at the Capitol — while members like myself were told to duck under chairs in the House Gallery as a violent mob broke down the doors of the House Chambers — was a violent extremist attack on our democracy,” Rep. Josh Gottheimer said Friday as he introduced the Stopping Domestic Terrorists Act. “We can never let that happen again.”

Gottheimer’s bill would double the maximum prison term for the crime of insurrection from 10 years to 20, the Washington Examiner reported.

But as of now, the bill would be a symbolic gesture.

Although 119 arrests have been made in the deadly siege at the nation’s capital, according to the Department of Justice, no charges of insurrection have yet been filed.

Instead, suspects from multiple states are facing charges like unlawful entry, civil disorder, and theft of government property.
