Might be worth reading the (rather hysterical) article properly:
"The pause will not effect the federal holidays for King's birthday or Juneteenth, the memo adds. "
Otherwise they are just not observing a load of pointless junk events:
Martin Luther King Jr.'s birthday in January, Black History Month in February, Women's History Month in March, Holocaust Day/Days of Remembrance and Asian American Pacific Islander Heritage Month in May, Pride and Juneteenth in June, Women's Equality Day in August, National Hispanic Heritage Month in September and October, National Disability Employment Awareness Month in October, and National American Indian Heritage Month in November.
