Sen. Craig said he will pursue "additional legal options."
WASHINGTON (CNN) - Idaho Sen. Larry Craig said Thursday he will remain in the Senate and study "additional legal options" after a Minnesota judge refused to throw out his August guilty plea stemming from an airport sex sting.
In a statement from his office, the three-term Republican said he was "extremely disappointed" in Thursday's ruling.
"I am innocent of the charges against me. I continue to work with my legal team to explore my additional legal options," he said.
He said the past few weeks have shown that "it is possible for me to work here effectively," and said any replacement appointed by Idaho's governor would not have the seniority and committee assignments "that are valuable to Idaho."
