A group of pro-Trump activists led by Ginni Thomas has reportedly compiled lists of “disloyal” government officials it wants sacked.
It is alleged that Ms Thomas, the wife of Supreme Court Justice Clarence Thomas, is part of a network of conservative activists called Groundswell, which has close ties to Trump and senior administration officials.
Dozens of women protested over the murder of a seven-year-old girl in the Mexican capital, a case that generated anger and outrage.
As well as writing on “disloyal” officials in their memos, Groundswell is also thought to recommend people to replace current officials.
Ms Thomas has been criticised for plugging overtly partisan messages, which some suggest is inappropriate for the spouse of a Supreme Court justice.
She and other hard-right activists met with Mr Trump in January, according to a New York Times report.
Elsewhere, the Supreme Court voted on Friday evening to allow a new rule which limits the ability of low-income immigrants to enter the US. »
