Just one month after President Barack Obama signed the Cybersecurity Information Sharing Act (CISA) of 2015 into law, a bipartisan coalition of U.S. House members led by Rep. Justin Amash (R-Mich.) introduced a bill that would repeal the legislation.

Supporters of the original act, including the Obama administration, argue the bill creates a system for the voluntary sharing of cyberthreat intelligence between private corporate entities and government agencies. But opponents, including some privacy advocates, insist that it infringes on citizens' privacy, and also that it was furtively slipped into a larger omnibus appropriates bill that was signed into law on Dec. 18, 2015.

Amash was joined by Rep. John Conyers (D-Mich.), Rep. Zoe Lofgren (D-Calif.), Rep. Thomas Massie (R-Ky.), Rep. Ted Poe (R-Tex.), and Rep. Jared Polis (D-Colo.).
