JUDY WOODRUFF:

President Trump is now under scrutiny for possible obstruction of justice, and he's fighting back.

This follows news reports that special counsel Bob Mueller has broadened his probe originally focused on Russia meddling in the election. On Twitter today, the president complained — quote — "They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice. Nice."

Later, Mr. Trump charged that Hillary Clinton committed a list of infractions, and was cleared anyway.

There's also word that Vice President Mike Pence has hired outside legal counsel to deal with the Russia investigations. His office tells The Washington Post that former U.S. attorney Richard Cullen will handle inquiries from congressional committees and the special counsel. The president hired his own private lawyer last month.

We will examine all of this, and talk to the vice chairman of the Senate Intelligence Committee, Senator Mark Warner, right after the news summary.

The U.S. Senate today overwhelmingly approved new sanctions against both Iran and Russia. The overall bill is aimed at Iran's missile program. An amendment expands sanctions on Russia for meddling in last year's election.

Senate Minority Leader Chuck Schumer said today it sends a message to Russian President Vladimir Putin and to President Trump.
