It still was not a "public use" project, which is what the Constitution requires for eminent domain.
If the Republicans are so upset about Kelo where has the constitutional amendment draft been to overturn it?
A number of GOP controlled states have passed statutes to limit the effect of Kelo in their states. And there have been several bills introduced into Congress to overturn Kelo, but they have all been killed by Reid and the Dems in the Senate.
Laws can't overrule a court decision like an amendment does.
I am against the Kelo decision but the Trump case predates that by a decade.
And it seems the same people bringing this up to take down Trump don't want to bring up the keystone pipeline that will take private land to build a private pipeline owned by a Canadian company.
