The scattershot nature of the Trump team's comments and legal challenges to the election have caused speculation about what litigation he hopes to pursue and what allies are behind him. I have a couple answers to that though this is all fast moving and it's hard to be definitive.

A source familiar with the Trump team's legal strategy tells me there main Supreme Court litigation is the case about the Pennsylvania Supreme Court decision that granted a three day extension letting officials there count some mailed ballots received up to tomorrow

Jay Sekulow, who has a winning Supreme Court record and helped lead the successful impeachment defense is the attorney of record for the Trump campaign in that case.

Along with his work on the Supreme Court case about the Pennsylvania count, Sekulow tells me he is "involved with overall strategy" for the campaign's legal challenges.

The PA case includes the states Republican Party, which is being repped by Jones Day, and a conservative group, the Honest Elections Project, repped by David Rivkin of Baker Hostetler.

Sekulow filed a motion to intervene on the Trump campaign's behalf yesterday. The PA consented to that intervention this evening.

This case began in late September. The Supreme Court deadlocked on it the following month. The Republicans are hoping they will hear it now with Amy Coney Barrett as a potentially deciding vote.

My understanding is that there are only about 100,000 PA votes at stake in this case. It won't matter if PA is not decisive or if the margin there exceeds that total.

It is not clear that the Trump camp will have another Supreme Court challenge if Biden wins enough electoral votes to render PA irrelevant and there are still multiple ways that could happen.
