In the first place, it's not up to Congress. (And just so you know, Democrats control the House.)
In the second place, there's an excellent chance that little Donnie will not win in 2020. He's trailing behind the leading Democrats in the polls. People are getting well and truly sick of him.

Even if the justices do hear them, the Chief Justice, among others, has an abiding respect for precedent. And I doubt he and his colleagues want to spark a civil war.
