The strongest evidence comes from the U.S. Bureau of Labor Statistics. 'Table B-1. Employees on nonfarm payrolls by industry sector and selected industry detail - March 2026' explicitly shows federal government employment falling from 2.676 million in February 2026 to 2.658 million in March 2026, which verifies the claimed 18,000 decline. 'Employment Situation Summary - March 2026' also states that federal government employment continued to decline. The exact level rounds to 2.66 million, matching the statement. The remaining part of the claim, that this was the lowest level since 1966, is supported here only by the secondary source 'This is the Weirdest US Labor Market I’ve Ever Seen,' which says the BLS data put federal employment at its lowest since 1966. I did not fetch a primary historical BLS series in this run to independently confirm that historical comparison. I also did not find fetched evidence substantiating the exact '14-month streak of job losses' wording. So the statement is well-supported on the March decline and 2.66 million figure, somewhat supported on the 1966 comparison, and insufficiently verified on the 14-month streak.
