U.S. Sen. Susan Collins isn't running for governor of Maine next year.
In an announcement Friday, Collins said the governor job is attractive but said she wants to "continue to play a key role" in issues like Russian interference in U.S. elections, North Korea and health care.
Collins also mentioned her seniority in the Senate and her senior position on the Senate appropriations committee.
Staying in the Senate means Collins can continue to wield her influence.
