WASHINGTON (Reuters) - U.S. House Democratic leader Nancy Pelosi endorsed Hillary Clinton for the presidency on Tuesday as voters in California, the nation's most populous state, head to the polls.


In a statement, the California Democrat praised the former U.S. secretary of state and called on supporters of rival Bernie Sanders "to advance our shared fight."
