Ironically, just two days ago, Council President Donald Tusk criticized Donald Trump's recent executive order putting a moratorium on new visas for nationals of seven particularly risky seedbeds of terrorism, calling the U.S. President a "demagogue" who poses an "existential threat" to the EU.
Tusk said those factors "as well as worrying declarations by the new American administration all make our future highly unpredictable".

Amnesty International, Human Rights Watch and the U.N. High Commissioner for Human Rights have all criticized Libya's human rights record.
