The US has issued a domestic terrorism bulletin over a "heightened threat environment" following the inauguration of Joe Biden.
It comes as Donald Trump begins to emerge from his post-White House isolation with plans to meet with Republican House minority leader Kevin McCarthy in Florida. While Trump faces a second impeachment, it has been called "dead on arrival" after most GOP Senators voted to declare it unconstitutional.
Trump remains popular within the party, with a new Morning Consult poll showing 81 per cent Republicans have a positive opinion of the former president and half believing he should play a significant role in the GOP's future.
Biden, meanwhile, signed three executive actions to tackle climate change, including the pause of new oil and gas leases being granted on federal lands. Another directs the government to acquire electric vehicles and a third formally establishing an office of domestic climate policy under John Kerry and Gina McCarthy.
