WASHINGTON (Reuters) - Persistent Federal Reserve critic Representative Ron Paul plans to hold a hearing on the U.S. central bank's emergency loans to the branches of non-U.S. banks, his spokeswoman said on Saturday. "I was surprised and deeply disturbed ... to learn the staggering amount of money that went to foreign banks," Paul said in a statement. "These lending activities provided no benefit to American taxpayers, the American economy, or even directly to American banks," he said.
