U.S. President Joe Biden unleashed a full-scale assault on his predecessor’s legacy Wednesday, acting hours after taking the oath of office to sweep aside former President Donald Trump’s pandemic response, reverse his environmental agenda, tear down his anti-immigration policies, bolster the sluggish economic recovery and restore federal efforts aimed at promoting diversity.

Moving with an urgency not seen from any other modern president, Biden signed 17 executive orders, memorandums and proclamations from the Oval Office on Wednesday afternoon. Among the steps the president took were orders to rejoin the Paris climate accord and end Trump’s travel ban on predominantly Muslim and African countries.

Individually, the actions are targeted at what the president views as specific, egregious abuses by Trump during four tumultuous years. Collectively, Biden’s assertive use of executive authority was intended to be a hefty and visible down payment on one of his primary goals: to, as his top advisers described it, "reverse the gravest damages” done to the country by Trump.
