The GSA has not yet "ascertained" that Biden is the Pres elect and thus hasn't granted access for

As a rule, the GSA avoids any hint of partisanship. Even as the media declared Biden the winner on Saturday, the GSA was reluctant to immediately follow, saying in a statement that “an ascertainment has not yet been made. GSA and its Administrator will continue to abide by, and fulfill, all requirements under the law.” Every passing day, however, also stalls what was already a historically difficult transition. Making matters even more complicated, the law on the subject is vague and leaves it up to Murphy to determine when Biden is officially president-elect.

Murphy could play it safe and wait until December 14, when the Electoral College is set to cast their ballots for the president. But doing so could also significantly hamper the Biden transition effort and leave them scrambling amid dueling public health and economic crises.
