President Donald Trump’s efforts to pressure Ukraine into investigating a top rival in the 2020 U.S. presidential election prompted Speaker Nancy Pelosi and other Democrats in the House of Representatives to move ahead with an impeachment inquiry, threatening his presidency.
The scandal has also featured an extensive cast of Ukrainian officials.
Here are some of the other main American players in the drama.
Trump’s personal attorney, a former New York mayor and 2008 presidential candidate, is a central figure in a scandal that has led to the impeachment inquiry.
Acting independently of the U.S. government, Giuliani has pressed Ukrainian officials to investigate one of Trump’s main rivals in the 2020 presidential election, former Vice President Joe Biden.
Giuliani says Biden improperly pressured Ukraine to fire its top prosecutor, Viktor Shokin, in order to stop an investigation into a company that put his son, Hunter, on its board.
In a July 25 phone call, Trump urged Ukraine President Volodymyr Zelenskiy to meet with Giuliani and U.S. Attorney General William Barr to discuss the president’s concerns about Biden.
The Democratic-led House Intelligence Committee has given Giuliani until Oct. 15 to turn over documents related to his work.
