White House press secretary Sarah Huckabee Sanders will answer questions from reporters Tuesday afternoon.

The briefing comes just hours after the Trump administration formally proposed to scrap the Obama administration’s signature climate change rule for power plants.

Environmental Protection Agency chief Scott Pruitt signed the notice Tuesday, arguing that former President Obama’s 2015 rule, dubbed the Clean Power Plan, exceeds the agency’s authority under the Clean Air Act.

The press briefing also comes as President Trump is embroiled in a war of words with both the NFL and Sen. Bob Corker (R-Tenn.).

The briefing is scheduled to begin at 1:45 p.m.
