Signed December 27, 2016
This executive order supersedes a previous order (13715) dated December 17, 2015. Thus, it appears to be a fairly routine adjustment of pay rates for various executive officers, some legislative and judicial employees, as well as all “uniformed employees” that include the military.
Several schedules (presumably lists of categories and rates) are referred to in the order as attached documents, but they do not appear on the White House site.
The National Defense Authorization Act for Fiscal Year 2017 (signed December 23, 2016) is cited as part of the authority for establishing the pay rates in this order.
