Mogherini visited Washington on February 9-10 for the first time since Donald Trump became president, meeting both with Tillerson and Michael Flynn, Trump's national security adviser, RFE/RL reported.
Mogherini said she and Tillerson had an "open exchange on many dossiers," including "transatlantic relations, the common challenge of countering terrorism, the ongoing work to strengthen European defense, relations with Russia, the Iran nuclear deal, and the main crises, from Ukraine to Syria," she said.
No details of the discussions were available.

Trump has expressed openness to working more closely with Russia, a stance that has rattled European allies, while Tillerson had significant business ties with Russia when he was chief executive of ExxonMobil. But during his confirmation hearings, Tillerson called Russia a "bad actor."
