Rudolph W. Giuliani, whose actions as President Trump’s personal lawyer have helped set in motion an impeachment inquiry, is set to appear as a paid speaker at a Kremlin-backed conference in Armenia on Tuesday — an event expected to include the participation of Russian President Vladi­mir Putin and other top Russian officials.

Giuliani confirmed to The Washington Post on Friday that he plans to take part in a panel at the conference sponsored by Russia and the Moscow-based Eurasian Economic Union, a trade alliance launched by Putin in 2014 as a counterweight to the European Union.

According to an agenda for the event posted online, Giuliani is set to participate in a panel led by Sergey Glazyev, a longtime Putin adviser who has been under U.S. sanctions since Russia’s invasion of Ukraine five years ago.

Update: After the WaPo story was published, Giuliani decided not to attend the event.
