North Dakota Republican U.S. Sen. John Hoeven says more information is needed about what President Donald Trump said during a private meeting with Russian officials last week.

Trump on Tuesday defended his right to share "facts pertaining to terrorism" and airline safety with Russia. Trump's tweets did not say whether he revealed classified information about the Islamic State group.

Hoeven says a "clear explanation" is needed of what was discussed.

Republican U.S. Rep. Kevin Cramer says a president has the right to discuss issues with Russia. But he says a president "shouldn't give away the playbook" when it comes to classified information.

Cramer says he doesn't believe Trump did that.
