"He certainly is good at being able to elude law enforcement," said Garrett, an ABC News consultant. "However, he's very blatant in some of these frauds and it would have taken not that much work, I believe, by an investigator, to have found him."
"I guess the real question is why didn't the FBI do that years ago, because it's really their case," he added.
Beyond their note of congratulations, the FBI declined to comment either about the arrest or about the unexplained espionage investigation.
As to how a fugitive with a false identity got so close to a sitting president, the Secret Service told ABC News that name checks "are just one layer of security measures put in place to ensure the safety of our protectees and venues."
"We will not comment specifically about these measures due to operational security, methods and means," Secret Service spokesperson Max Milien said.
