[5] A memoir written by Yeltsin, as reported by The New York Times,[6] credited her with advising against "banning Communist Party, dissolving Parliament and postponing presidential elections" in 1996.

She became the keystone in a small group of advisors known as "The Family", although the others (Alexander Voloshin and Valentin Yumashev) were not Yeltsin relatives.

She is portrayed in the 2003 satirical comedy Spinning Boris, based on the real experiences of U.S. political consultants in the 1996 campaign.

[11] In 1980, Yeltsina married fellow Moscow State University student, Vilen Ayratovich Khairullin.

In 2001, Tatyana married her fellow presidential adviser Valentin Yumashev,[15] and flew to London to have a baby, daughter Maria.
