"Typically, DC Circuit Court arguments run smoothly, one after another until three cases have been argued publicly, starting at 9:30 am in a large, portrait-lined courtroom on the Fifth Floor of the federal courthouse on Constitution Avenue. But after Circuit judges David Tatel, Thomas Griffith and Stephen William – who coincidentally has written two books on Russian history – heard an immigration-related case Friday morning, the courthouse security went into lockdown mode.

Tatel, Griffith and Williams took a brief recess, indicating they'd return to the courtroom shortly.

Then, security officers cleared the appeals courtroom, allowing only about a dozen law clerks working for federal judges to stay behind, including at least one who assists Howell with her cases.

Security guards also cleared the vestibule to the courtroom and checked the coat closet where attorneys coming to listen to arguments stash their belongings. They locked the door leading to the attorneys' lounge on that floor and shooed the more than 20 reporters prowling the hall away from the elevator bank and told them to vacate the nearby stairwells. At one point, even an elevator wouldn't open its doors on the fifth floor.

The entire level of the building on which the appeals court is housed was locked down."
