President-elect Donald Trump held his first press conference in six months this morning, and Trump’s attorney, Sheri Dillon, spoke for several minutes about his business.

Dillon said that Trump will be handing over control of his organization to his adult children. However, he will not be putting the organization into a blind trust, and Dillon said doing so would not be feasible.

“The conflicts of interests laws simply do not apply to the president or the vice president,” Dillon added.

So who is Sheri Dillon, and what is her relationship with Donald Trump? Here’s what you need to know about her.

1. She Is a Partner at Morgan Lewis & Bockius

Sheri Dillon is a partner at the global law firm Morgan, Lewis & Bockius, which has its headquarters in Philadelphia, Pennsylvania. Dillon, however, works in Washington, D.C.

In May 2016, this law firm was named Russia Law Firm of the Year by Chambers & Partners. Morgan Lewis has an office in Moscow.

Hillary Clinton also made use of Morgan Lewis during her presidential campaign; James Hamilton, a partner at Morgan Lewis, helped Clinton vet her possible running mates, according to The New York Times.

Morgan, Lewis & Bockius happens to be the law firm where Texas Senator Ted Cruz previously worked. Cruz was a partner at the firm from 2008 to 2013, and he represented a variety of corporate clients.

Dillon was previously a partner for Vinson & Elkins, Bingham McCutchen and McKee Nelson LLP.

In addition, Sheri Dillon serves as the director and president of the Washington D.C. Center for Public Interest Tax Law. This is a non-profit organization that provides pro bono representation to low-income individuals with cases in the U.S. Tax Court. Dillon has served in this position since January 2016. She also helped launch the University of the District of Columbia’s Low-Income Taxpayer Clinic, where students represent low-income clients on tax issues.

2. She Has Worked as a Trump’s Tax Counsel Since 2005

Dillon advises wealthy individuals on controversial tax matters, according to her Chambers and Partners profile. She also has experience with IRS audits.

Since 2005, Dillon has served as a tax counsel for The Trump Organization, advising Trump long before he launched his bid for the presidency, according to a letter released by the Trump campaign in March 2016.

Also working with Dillon as tax counsel for The Trump Organization since 2005 has been William F. Nelson, who is employed with Morgan, Lewis & Bockius LLP as well.

3. She Graduated From Georgetown University Law Center

Sheri Dillon’s alma mater is Georgetown University Law Center, which is located in Washington, D.C.

Dillon is a graduate of the class of 1999, according to her LinkedIn page. Dillon also graduated from the University of Missouri in 1984 with a B.A. and then in 1986 with a Master of Public Policy degree, according to her Morgan Lewis profile.

Dillon regularly gives lectures on tax issues; according to her Morgan Lewis profile, she has spoken before the Tax Executives Institute, the Federal Bar Association, the American Bar Association Section of Taxation, and the D.C. Bar Section of Taxation.

In addition, Dillon has taught partnership taxation at the Columbus School of Law, which is the law school of the Catholic University of America in Washington, D.C.

4. She Says Trump’s Tax Returns From 2002 to 2008 Are No Longer Being Examined by the IRS

Donald Trump continues to say that he cannot release his tax returns because they are being audited by the IRS and that he has been advised not to release his returns while they are under audit.

However, in a letter released by the Trump campaign in March, Sheri Dillon said that Trump’s returns from the years 2002 through 2008 are not currently under audit.

“Examinations of your tax returns for the years 2002 through 2008 have been closed administratively by agreement with the IRS without assessment or payment, on a net basis, of any deficiency,” the letter read.

Trump has said that he will not release the tax returns from these years either because “they’re all linked,” according to The Washington Post.

5. She Donated to Hillary Clinton in 2007

In 2007, Sheri Dillon donated $1,500 to the campaign of Hillary Clinton, according to LawNewz.

Dillon did not, however, donate to any candidate during the 2016 election.

Of course, Donald Trump himself has also donated to Hillary Clinton as recently as 2009, when he gave $100,000 to the Clinton Foundation. This money was an “unrestricted gift” from the Trump Foundation, according to the Washington Post.
