evidence: Under President Donald Trump, the unemployment rate was 4% or under for 24 months, compared with 18 months under Biden. [...] The longest stretch in which the unemployment rate was "under 4%" during Trump’s tenure was 13 months, from February 2019 to February 2020, right before the coronavirus pandemic arrived in the U.S. and sent unemployment skyrocketing. That would be shorter than the streak under Biden. Biden’s statement would’ve been wrong had he said unemployment has been "4% or below" for the longest stretch in 50 years. That distinction goes to Trump, who oversaw an unemployment rate of 4% or under for 24 months.
