evidence: Trump’s administration "added more to the national debt than any presidential term in American history," Biden said. "Check the numbers, folks." [...] The day after Biden’s speech, the Committee for a Responsible Federal Budget, a Washington-based group that studies fiscal policy, wrote that Trump had signed legislation or executive orders that added $8.4 trillion of new borrowing over 10 years, about half of it in pandemic relief. [...] Trump did accumulate more debt during his term than any previous president’s single term, and also more than Biden has accumulated so far in his tenure. But Biden’s tenure isn’t over yet.
