Oh, no one ever cared about the East Wing.

You're not seeing any East-Wing-specific drama.

From the Wikipedia article East Wing, here's the humble story of the part of the White House you were never thinking about before:

President Thomas Jefferson added colonnaded terraces to the east and west sides of the White House, but no actual wings. Under President Andrew Jackson in 1834, running water was piped in from a spring and pumped up into the east terrace in metal tubes. These ran through the walls and protruded into the rooms, controlled by spigots. Initially, the water was for washing items, but soon the first bathing rooms were created, in the ground-level east colonnade. President Martin Van Buren had shower baths installed here. The East Terrace was removed in 1866. For many years, a greenhouse occupied the east grounds of the White House.

The first small East Wing was built during the Theodore Roosevelt renovations, as an entrance for formal and public visitors. This served mainly as an entrance for guests during large social gatherings, when it was necessary to accommodate many cars and carriages. Its primary feature was the long cloak room with spots for coats and hats of the ladies and gentlemen.

The East Wing as it exists today is a two-story structureand was added to the White House in 1942 primarily to cover the construction of an underground bunker, now known as the Presidential Emergency Operations Center(PEOC). Around the same time, Theodore Roosevelt's coatroom became the movie theater. Later, offices for correspondence, calligraphers and the social secretary were placed in the East Wing. Eleanor Roosevelt employed the first social secretary.[1]

Rosalynn Carter, in 1977, was the first first lady to keep her own office in the East Wing. Today, the social secretary prepares all of the invitations and written correspondence for every event held at the White House.
