After she died in 1881, more than 200 marble statues, bronze sculptures, fine furniture, and paintings in the house were donated to the Corcoran Gallery of Art.

Phoebe Warren Tayloe's niece, Elizabeth H. Price, inherited the house in 1882 and later sold it to Senator Don Cameron of Pennsylvania for $60,000 in 1887.

In around 1896, the U.S. Senate passed legislation which would have made the building the official residence of the Vice President of the United States, but the House of Representatives failed to act on the bill.

Hobart's failing health led the family to leave the Tayloe House in the fall of 1899 and Cameron then leased the home to Republican Senator Mark Hanna from January 1900 to 1902.

Hanna's important political discussions of the moment with William McKinley and Theodore Roosevelt over substantial breakfasts of corned beef hash and pancakes became famous.

First Lady Jacqueline Kennedy was instrumental in persuading architect John Carl Warnecke, a friend of her husband, to create a design that would incorporate the new buildings with the old, based on the architectural theory of contextualism.

[4] Although Tayloe preferred to live at Windsor, his estate in King George County, Virginia, his wife asked that they move into the city, where she was more comfortable.

Tayloe had a strong political disagreement with the newly elected President, Andrew Jackson, and refused to move into the home.

[23] Sickles rushed out into the park, drew a single pistol, and shot the unarmed Key three times while the other man pleaded for his life.

[20] Key's spirit, eyewitnesses and authors claim, now haunts Lafayette Square and can be seen on dark nights near the spot where he was shot.

[26] Presidents John Quincy Adams, Martin Van Buren, William Henry Harrison, Zachary Taylor, and Millard Fillmore also were frequent guests.

[29] After she died in 1881, more than 200 marble statues, bronze sculptures, items of fine furniture, and paintings in the house were donated to the Corcoran Gallery of Art.

[38] About 1896, the U.S. Senate passed legislation which would have made the building the official residence of the Vice President of the United States, but the House of Representatives failed to act on the bill.

[46] The home was also host to Hanna's famous large breakfasts of corned beef hash and pancakes, over which the most important political decisions of the moment would be made.

"[15][26][46] It was at just such a breakfast on March 10, 1902, that J. P. Morgan asked Senator Hanna whether the United States government had any intention of filing an antitrust lawsuit against the recently formed Northern Securities Company.

[51] The Cosmos Club vacated the Tayloe House in 1952 to move to new headquarters in the Townsend Mansion at 2121 Massachusetts Avenue NW,[53] at which time the building was purchased by the U.S. government and used for offices.

[57] The Park Commission's charge was to reconcile competing visions for the development of Washington, D.C., and in particular the National Mall and adjacent areas.

[60] At nearby 1616 H Street NW, the Brookings Institution purchased the rear garden from the private owners of the Decatur House and built an eight-story Modernist office building there.

[62] Opposition to the demolition of the Tayloe House and other buildings on Lafayette Square began forming shortly after the plan to raze the structures was announced.

Senators James E. Murray and Wayne Morse, several members of the House of Representatives, and citizens of the District of Columbia lobbied to defeat the legislation authorizing the demolition of the buildings.

"[64] The AIA established a committee to develop plans to save the buildings and adapt the new structures so that they incorporated the style and feel of the older homes.

[67] In February 1962, First Lady Jacqueline Kennedy lobbied General Services Administration (GSA) director Bernard L. Boutin to stop the demolition and adopt a different design plan.

[69] Mrs. Kennedy enlisted architect John Carl Warnecke, a friend of her husband's who happened to be in town that weekend,[70] to create a design which would incorporate the new buildings with the old.

[74] Warnecke's design for the Markey National Courts Building was to create tall, flat structures in red brick which would serve as relatively unobtrusive backgrounds to the lighter-colored residential homes like the Cutts-Madison House.
