Newspaper report says shutting down Gitmo would include a $600 million price tag
Obama reportedly rejected the Pentagon's plan and asked for revisions
It's one of many hurdles the President has faced in his quest to close the military prison
Since before he was elected, President Obama pledged to shut down the military prison at Guantanamo Bay, Cuba.
Now a newspaper report says Obama’s plans have hit a new hurdle – it may be too expensive to close.
The Wall Street Journal reports the White House rejected a Pentagon plan to close Gitmo and build a new U.S. prison in its place, because the cost estimates were too high.
