US President-elect Joe Biden will cap a busy day of inauguration pageantry by using the powers of his new office to push policy changes on housing, student loans, climate change and immigration, a top aide said on Saturday. Biden, who campaigned on a raft of promises to undo President Donald Trump’s legacy even before the novel coronavirus pandemic walloped the nation, will unveil “roughly a dozen” previously promised executive actions on Wednesday, incoming Biden chief of staff Ron Klain said in a memo distributed to reporters. The actions to be taken on Wednesday include rejoining the Paris climate accords, reversing a travel ban on several majority Muslim countries, extending a pause on federal student loan payments, halting evictions and foreclosures, as well as mandating masks in inter-state travel and on federal property. All of the measures were previously announced. Most of the measures are a reversal of policies Trump pursued and do not require congressional action. But Biden will also unveil a long-expected immigration proposal that would provide a pathway to citizenship for millions of undocumented immigrants that does require congressional action. That measure, as well as Biden’s recent proposal for $1.9 trillion in spending on COVID vaccinations and economic stimulus, face uphill battles in a Congress narrowly controlled by Biden’s fellow Democrats.
