WASHINGTON (AP) — Calling it a "very special day," Melania Trump helped plant a sapling from an Eisenhower-era tree on the south grounds of the White House.

The White House says the 12- to 14-foot sapling came from the original Eisenhower oak near an East Wing garden created by former first lady Jacqueline Kennedy. It replaces a tree that groundskeepers removed after it was felled during a violent windstorm in March.

The first lady was joined Monday by Mary Jean Eisenhower, granddaughter of President Dwight D. Eisenhower, and Richard Emory Gatchell, Jr., a fifth-generation grandson of President James Monroe.

The White House says the planting was done in conjunction with the White House Historical Association's Presidential Sites Summit. The summit is a days-long gathering in Washington that draws many descendants of past presidents.
