Two leading senators are poised to announce a draft bill that would impose penalties for refusing to comply with a court order.
Sens. Richard Burr (R-NC) and Dianne Feinstein (D-CA) will reveal the legislation as early as next week, according to sources speaking to Reuters.
According to the news agency, the unreleased legislation would not seek criminal penalties.
The bill echos similar draft proposals announced at the state level in California and New York, both of which would prohibit the sale of encrypted devices that can't be opened by law enforcement.
But the bill faces an uphill battle, given the political explosion in legislation hitting state and national legislatures.
