A bipartisan group of senators plans to introduce legislation to overhaul how the government classifies and protects its most sensitive national-security secrets, according to people familiar with the matter. Complementary bills would reduce the amount of classified material by making it easier to downgrade or make it public while also looking to plug perceived gaps in the existing security-clearance process. Despite the widespread agreement, policymakers have not coalesced around specific overhaul proposals, and it is unclear if the Biden administration would support the congressional action.

Chong learned about a threat to his family in Hong Kong from a newspaper and slammed the Trudeau government for inaction. Leyland Cecco reports for the Guardian
