Joe Biden's First 100 Days: What Did He Promise and What Did He Deliver? On 4/29/21 at 6:00 AM EDT President Joe Biden has largely kept a laser-like focus on combating the coronavirus pandemic and promoting his economic recovery package as he nears the 100-day mark in office, while setting aside or delaying dozens of promises he made on the campaign trail. Thursday marks the milestone, which often seen as a critical point in any president's first term and shows what priorities became the administration's focus. Biden entered the White House after with a stunted transition period because of a lack of cooperation from the Trump administration, as Donald Trump refused to concede the election, and because of the pandemic. His start was further complicated because Democrats hold razor-thin margins of control in the U.S. House and Senate amid heightened partisanship.
