Based on all available evidence, Egypt gave Trump $10 million in cash a few days before his 2017 inauguration (that’s 200 pounds of $100 bills). The FBI and DOJ started investigating this in 2019, but attorney general Bill Barr shut that down. Trump then changed US policy in Egypt’s favor.
Note that Sen. Bob Menendez was just convicted of likewise taking bribes from Egypt. This is their MO. https://wapo.st/3SxAkvO
