In a rational world, this is a quick turnaround, either declining to take the matter up because there are no real issues here and relying on the reasoning of Judge Chutkan’s ruling, or denying Trump’s motions outright. Both options can be done fast. But this nothing more than another slow walk to justice ! Let’s face it if they weren't prepared they shouldn't have appealed. 2) if they had no grounds to appeal they should not have appealed.
With great clarity it appears Trump and his lawyers don’t feel confident that his appointees to the Supreme Court will do his bidding as he expected when he appointed them. But never underestimate what next comes of Trumps rabbit hole!
