WASHINGTON (AP) — The Vietnam Veterans Memorial Fund has received a $10 million grant for its proposed education center in Washington.

The Washington Post (http://wapo.st/2lkzyDk) reported Tuesday that the fund says the grant from the Lilly Endowment is the largest single cash donation in the fund’s 37-year history.

It has been trying to raise money to build the underground Education Center next to its memorial on the Mall since 2003.
