The revelation late Monday that Sen. Larry Craig (R-Idaho) was arrested nearly three months ago for allegedly making sexual advances in a men's room raises the issue of how such an action could occur without the press reporting it.

Even Roll Call reporter John McArdle, who broke the story late Monday, admits he only received word of the arrest and subsequent guilty plea via a tip last week.

"You would think in the 24-hour news cycle, something like this would slip through," said McArdle, a four-year veteran of the Capitol Hill daily. "He wanted to keep it quiet, and he almost got away with it."

Even more surprising is that the unreported arrest occurred at a time when Craig was under scrutiny following previous allegations of gay relationships and sexual advances dating back to late 2006, when a blogger accused Craig of having relationships with men. The conservative senator has long denied the allegations.
