As their impeachment inquiry into President Donald Trump picks up steam, House Democrats have subpoenaed Trump’s personal lawyer Rudy Giuliani for documents related to his interactions with Ukrainian officials
The House Intelligence, Foreign Affairs and Oversight and Reform panels announced the subpoena Monday as they examine Trump’s efforts to have Ukraine investigate political rival Joe Biden, his family, and how Giuliani assisted in that effort.
The Democrats have also requested information from three of Giuliani’s associates. Giuliani subpoena follows one issued late Friday to Secretary of State Mike Pompeo for documents related to the impeachment inquiry.
The president’s allies fanned out across the Sunday talk shows espousing different approaches to the rough transcript and whistleblower complaint at the heart of the proceedings.
The whistleblower says Trump tried to pressure the president of Ukraine to investigate Hunter Biden, a son of Democratic presidential contender Joe Biden.
Giuliani, tried deflection by insisting the real story is a debunked conspiracy theory. Senior presidential adviser Stephen Miller said “deep state” figures are to blame. Ohio congressman Jim Jordan said Biden’s son improperly profited from his father’s position. However, there’s no evidence of that.
Trump himself tweeted he should be able to meet his accuser, “especially when this accuser, the so-called “Whistleblower,” represented a perfect conversation with a foreign leader in a totally inaccurate and fraudulent way.”
A top House Democrat said he expects the still-anonymous whistleblower is to testify “very soon.”
