Suicide hot line got calls from 22,000 veterans

The hot line receives up to 250 calls per day - double the average number calling when it began. Kemp said callers are divided evenly between veterans from the Iraq, Afghanistan and Vietnam wars. Richard McKeon, public health adviser for SAMHSA, said 10 to 20 of the 1,575 calls received each week have to be rerouted to high-volume backup call centers throughout the country.
