A top European Union official has warned the United States against interfering in European affairs. European Council President António Costa was reacting Monday to the Trump administration's new national security strategy. The document criticizes European allies and offers tacit support to far-right parties in Europe. Costa emphasized that only European citizens can choose their political leaders. The strategy released Friday questions Europe's free speech and migration policies. It underlines the importance of ending Russia's war in Ukraine and improving U.S.-Russia relations. But Costa says it focuses chiefly on the end of hostilities rather than peace and on the stability of relations with Russia.
