In a May 11, 2022 tweet, (self-described "public educator, academic, columnist, and policy adviser") Richard Javad Heydarian1,2 first asserts that China took the previous Philippine president Rodrigo Duterte "for a ride";
...China offered him billions of dollars, offered him concessions in the South China Sea where the two have maritime disputes. Guess what Christian (Amanpour), forget about debt-trap, this was "pledge trap".
and goes on to elaborate.
Later in the few minute clip, he discusses issues related to the future relationship between a (new) president Marcos (at the time Marcos had not yet won) and the US's Biden administration. But then there was this:
...and we know the Marcos' are quite notorious in America, they have a lot of court cases there. There are even suggestions that Marcos may have problems visiting America because of those court cases etcetera...
Question: Why might Philippine president Bongbong Marcos have problems visiting the US because of "court cases" there? What court cases might pose the greatest challenges to a Marcos visit to the US?
