Trump first offered to build a $100 million ballroom at the White House back in 2010, an offer to then-President Barack Obama that went unanswered. The East Wing of the White House will be "modernized" as part of the project. Offices there, including the one used by First Lady Melania Trump, will be temporarily relocated, Leavitt said.

The White House will undergo its most significant expansion in over a century with the construction of a new 90,000-square-foot ballroom.

President Trump is reshaping the White House grounds, replacing the iconic Rose Garden lawn with a stone patio and planning a $200 million ballroom in the East Wing.
