Secretary of State nominee Rex Tillerson expressed views on Wednesday at odds with President-elect Donald Trump's positions on key foreign policy issues like nuclear proliferation, trade deals, climate change and relations with Mexico.
In a nine-hour Senate confirmation hearing, the former chief executive of oil company Exxon Mobil said he favored maintaining U.S. sanctions against Russia for now and that NATO allies were right to be alarmed by Moscow's growing aggression.
Russia dominated much of the hearing because of concerns by Democrats and Republicans over Moscow's interference in the U.S. presidential election and its 2014 annexation of Crimea from Ukraine and involvement in the Syrian civil war.
Questions soon moved to the threat posed by Islamic State, China's behavior in the South China Sea, human rights and Tillerson's ability to make a clean break from a career at Exxon Mobil to become America's top diplomat.
Tillerson said his differences with Trump on some major issues would not necessarily put him at loggerheads with the White House.
