It's Maggie Hassan's last day as governor of New Hampshire.
The Democrat will resign at midnight so she can be sworn in as a U.S. Senator on Tuesday. Republican Senate President Chuck Morse will serve as governor until Gov.-elect Chris Sununu, also a Republican, is inaugurated Thursday.
Hassan on Tuesday will become only the second woman to serve as a state's governor and U.S. senator in the country's history. The other is a fellow Granite State, Democratic U.S. Sen. Jeanne Shaheen.
Hassan served two, two-year terms as New Hampshire's governor.
