President Donald Trump has been issuing conflicting claims when it comes to the Russian interference in the 2016 U.S. election. From claiming the Russian meddling is just a Democratic hoax, the billionaire shifted gears by accusing his predecessor, President Barack Obama, of colluding with Russia.

An indicator that White House officials are actually taking the Russia investigation seriously, despite Trump’s 3 a.m. tweets, is the growing legal teams of key personalities being investigated by special counsel Robert Mueller. The latest figure to hire his own private lawyer is presidential son-in-law and senior adviser Jared Kushner, Reuters reported.

Lawyer in Bill Clinton impeachment

Ironically, Abbe Lowell, the lawyer whom Kushner hired as his private attorney for the Russia investigation, ran unsuccessfully as a Democrat for the Maryland House of Delegates in 1982. More importantly, Lowell was the chief minority counsel to the Democrats when President Bill Clinton faced impeachment proceedings in the Monica Lewinsky scandal.

The former president is just one of the high-profile political investigations Lowell had handled. He also was the defense lawyer of Jack Abramoff, a Republican lobbyist, in a bribery case during the 2006 election campaign, Bloomberg reported. Another client of Lowell is Senator Bob Menendez, a New Jersey Democrat charged in an ongoing corruption and bribery case.

Besides Kushner, Trump, Vice President Mike Pence, and Attorney General Jeff Sessions are among the Trump administration officials who have retained the services of private lawyers for the Russia investigation. Trump, however, had insisted there was no collusion between his 2016 campaign and Russian officials.

Meeting with Kislyak

Special counsel Robert Mueller and his team are looking into Kushner’s meetings with Russian Ambassador to Washington Sergey Kislyak who is reportedly being recalled by Moscow. They had three undisclosed contacts during the campaign, one of which includes Kushner proposing the establishment of a back communications channel using the Russian embassy facility.

Kushner has another lawyer, Jamie Gorelick, who works at WilmerHale, a law firm where Mueller also worked until he was appointed the special counsel, Reuters reported. Gorelick said after Mueller left WilmerHale with three more lawyers from the firm, they asked Kushner to first get independent legal advice if the son-in-law of Trump should still continue to retain the service of WilmerHale as counsel.

Lowell is a graduate of the Columbia University in 1974 and Columbia Law School in 1977. He was assistant to Attorney General Benjamin Civiletti and taught law at Columbia University and Georgetown Law Center.
