WASHINGTON (CNN) - Sen. Larry Craig of Idaho made a surprise appearance Tuesday the U.S. Capitol, his first since the scandal broke last month over allegations he tried to solicit sex from an undercover police officer in a restroom at Minneapolis-St. Paul International Airport.
The Republican senator had a brief exchange with CNN's Ted Barrett at a Capitol entrance:
Barrett: "What brings you back to the Capitol today?"
Craig: "Go to work."
Barrett: "Are you intending to vote today, sir?"
Craig: "That's my plan."
Barrett: "Why decide to come back today?"
Craig: "Because I'm a serving United States Senator from Idaho."
Craig then stepped into the senators' dining room on the first floor of the Capitol. On the way he passed a visibly surprised Sen. Lindsey Graham, R-South Carolina, who gave Craig a big welcome back handshake.
Craig was later asked by reporters if his presence in the Capitol today means he will not resign.
The Idaho Republican responded, " no not at all - I'm here to work with my staff and my office and to work with my legal team."
Asked if he is confident about his court case, he said, "I have no opinion. I'd like to be."
Craig pleaded guilty Aug. 8 to one charge of disorderly conduct, then sought legal counsel to change his plea to not guilty. A hearing on the request is set for Sept. 26
When the case became public, Craig announced his intention to resign Sept. 30. But days later, it was announced that Craig would fight to overturn his conviction and may not resign. Craig filed papers Sept. 10 to withdraw his guilty plea.
On Monday, the American Civil Liberties Union filed a brief in court Monday calling Sen. Larry Craig's bathroom bust unconstitutional.
