Here's one action Bobby Kennedy took earlier in 1961. In March 1961, the Attorney General took steps to have Marcello deported to Guatemala (the country Marcello had falsely listed as his birthplace). On 4th April, Marcello was arrested by the authorities and taken forcibly to Guatemala.
Marcello was unceremoniously dumped in the hills in Guatemala without money or wallet and left to find his own way back to the states.
Thank so much for getting back to me. Marcello is quite familiar to me because I live in New Orleans and remember the papers being full of stories about him.
