"I am not in good health. I have a heart condition. I suffer from acute asthma... Needless to say I've been suffering deep anxiety every part of every day," he said.
"Mr President, for the majority of my adult life, for over 30 years I've served my country ... Now when I need my government it seems that I have been totally abandoned and forgotten."
The video could not be independently verified.
Weinstein was abducted in 2011 in the eastern city of Lahore where he worked for a U.S. consulting company.
