One of the so-called NatWest Three says he feels betrayed by the British government.
Gary Mulgrew told Scotland Today yesterday: "You get very jaded when you look at the politics behind this. That is incredibly disappointing.
"My disappointment is principally aimed at the British government, who we feel have abandoned us."
He added the legal proceedings had caused much stress for his ten-year-old son.
"It's tough on all the people around me. I don't think you can explain it to a ten-year-old. I've had a couple of difficult conversations with him when he's been trying to figure out when I'm coming home.
"I hope that it will end positively but the odds are stacked against us, we understand that. But what I'd like more than anything is that the truth emerges and if that happens then we'll be fine."
The men have been denied a request to return home to await trial over their alleged role in an Enron-related scandal.
US magistrate judge Stephen Smith ruled the trio must each find $1 million (£538,000) in bond money to remain free in the US.
Judge Smith denied their request to return home, saying he could not risk possible lengthy extradition proceedings if the men travelled outside US jurisdiction.
David Bermingham, Giles Darby and Mr Mulgrew, pleaded they should be allowed to return home to support their families and prepare their defence.
The men are accused of conspiring to defraud NatWest of $19 million (£10.2 million) in 2000.
The men were brought to Texas to face the charges last week after losing extradition appeals.
Although their trial is pencilled in for September 11th, a lengthy delay of over a year could ensue.
The men could be imprisoned during that time. They face up to 20 years in jail if found guilty of all the charges.
