This article is rather misleading in this one respect. The Obama Administration isn't "pressuring" Justice Sotomayor. When Justice Sotomayor issued the order in question, granting the temporary injunction, she requested that the Department of Justice file by today a written response, to the extent that Justice was arguing against the continuation of the injunction.
The Department of Justice has now filed its response, per Justice Sotomayor's request, that's all. That's how the process is supposed to work.
thanks for clearing it up....
