WASHINGTON D.C. (AP) UPDATE
Rex Tillerson says Islam is a "great faith" and he doesn't support the "blanket rejection" of people from the United States because of their religion.
President-elect Donald Trump said during the presidential campaign that if elected, he would implement a total ban on Muslims entering the United States. Trump has since proposed "extreme vetting."
Tillerson, Trump's choice for secretary of state, is telling the Senate Foreign Relations Committee the U.S. has to be "very clear-eyed" about the threat posed by the Islamic State and other extremist groups.
Rex Tillerson is telling senators he would work closely with Congress on any new Russia sanctions.
Trump's choice for secretary of state says he would cooperate "on the construct of new sanctions" after Moscow's alleged interference in the presidential election and aggression in other parts of the world.
Tillerson also says the Trump administration will be committed to seeking support from Congress for major military actions.
He says Trump believes "it is important that we not just lightly go into these conflicts" and would "seek the engagement and support" of Congress, either through a resolution or legislation to authorize the use of force.
Tillerson says: "It's much more powerful when the U.S. shows up with everyone aligned."
