Revealed: evidence shows huge mail slowdowns after Trump ally took over

The United States Postal Service (USPS) saw a severe decline in the rate of on-time delivery of first-class mail after Louis DeJoy took over as postmaster general, according to new data obtained by the Guardian that provides some of the most detailed insight yet into widespread mail delays this summer.

Shortly after taking the helm, DeJoy – a major Republican donor with no prior USPS experience – implemented operational changes he said were intended to make the financially beleaguered agency more efficient. Those changes included an effort to get USPS trucks to run on time and limiting extra trips to transport late mail, with the result that mail was often left behind.
