Didn't the President start signing a bill....noticed the $Billions involved then stopped signing...
He said he "scribbled the rest of the signature space so no one could add his name later"
It was a request for land and building for a new Jerusalem embassy.
Trump called the Ambassador who told Trump "we already have a building on a nice lot that I can convert to an embassy for $100K
Trump said that's a bit cheap......take a bit more"
You are most correct, and I think that the insight about the scribble could be spot on.... however, FWIW, it was the London embassy not Jerusalem embassy. Both stories current at the time, and easy to mix up.
