Twitter reacts to Department of Homeland Security Kirstjen Nielsen’s resignation/firing: “History will not judge her or the president kindly.” She will forever be remembered as the DHS secretary on whose watch scores of migrant children were separated from their parents and placed in cages on the US-Mexico border.

Donald Trump confirmed Nielsen’s ouster:  “Secretary of Homeland Security Kirstjen Nielsen will be leaving her position, and I would like to thank her for her service.”

He then named Kevin McAleenan, the current U.S. Customs and Border Protection Commissioner, as acting DHS secretary. Yep, another acting cabinet secretary from a man who bragged that he only hires the best people.

The ACLU tweeted:  “Kirstjen Nielsen served as Homeland Security Secretary during a sad and shameful chapter in the agency’s history. Nielsen oversaw civil rights and civil liberties violations that will go down as among the worst failures in Trump’s presidency.”

Democratic presidential candidate Sen. Kamala Harris tweeted:  “It was long past time for her to go.”
