The House Intelligence Committee has subpoenaed President Trump's personal attorney Rudy Giuliani for documents related to the Ukraine controversy to be turned over by Oct. 15.

Foreign Affairs Committee Chairman Eliot Engel, House Intelligence Committee Chairman Adam Schiff and Oversight Committee Chairman Elijah Cummings requested the documents in a letter they sent to Giuliani, according to their joint statement.

“A growing public record indicates that the President, his agent Rudy Giuliani, and others appear to have pressed the Ukrainian government to pursue two politically-motivated investigations,” the chairmen said in the statement. “The committees have reason to believe that you have information and documents relevant to these matters.”

What we know about Giuliani: The former New York City mayor has become a central figure in the unfolding scandal surrounding Trump's communications with Ukrainian President Volodymyr Zelensky that have led to a House impeachment inquiry into the President's conduct.

According to a White House-released transcript of a July call between the two leaders, Trump asked Zelensky to work with Giuliani and Attorney General William Barr to investigate former Vice President Joe Biden and his son, Hunter, though there is no evidence of wrongdoing by either Joe or Hunter Biden.
