Schiff, who chairs the Intelligence Committee, plans to resume the panel's investigation into possible collusion between the Trump campaign and Russian Federation.
"It's called presidential harassment", Trump said Wednesday. "And it really does hurt our country".
As an opening volley, the committee sent special counsel Robert Mueller, head of an independent agency created to investigate Russiagate, 50 interview transcripts, including talks with the committee by Trump's eldest son, Donald Trump Jr.; his son-in-law, Jared Kushner; his longtime spokeswoman, Hope Hicks; and his former bodyguard Keith Schiller, along with dozens of officials from both the Trump and Barack Obama administrations, the Washington Post noted. And I think that's fine because that's what they do. The California Democrat made the announcement after the committee voted to provide the special counsel's office with transcripts of interviews conducted as part of an investigation into Russian interference in the 2016 election. Democrats had previously pushed the GOP-led committee to release all of the transcripts to Mueller, but Republicans said Mueller hadn't requested them.
The committee voted on the step to release the transcripts Wednesday at its organizational meeting, where it announced it will relaunch the probe and focus on five key areas of interest.
Schiff told The Washington Post a year ago that there's a "whole set of potential financial conflicts of interests and emoluments problems that Congress will need to get to the bottom of" when it comes to the president's relationship with the Middle Eastern nation. Cohen pleaded guilty in November to lying to the House and Senate intelligence committees in a statement about his role in a Trump business proposal in Moscow, acknowledging that he misled lawmakers by saying he had abandoned the project in January 2016 when he actually continued pursuing it for months after that.
Cohen was scheduled to speak with the committee on Thursday.
The Intelligence panel previously agreed to send Mueller the closed-door testimony of Roger Stone, a long-time confidant of Trump.
In December, Cohen was sentenced by a federal judge in Manhattan to three years in prison for crimes including orchestrating hush payments to women in violation of campaign laws before the 2016 election.
The committee chair said he ultimately wants the testimonial transcripts released to the public.
The committee will also investigate whether any of the president's policy decisions were the result of foreign exploitation and whether any foreign actors are attempting to impede congressional or other investigations into those topics.
"Additionally, we call on our Democratic colleagues to grant our request to subpoena numerous witnesses whose testimony the Democrats had previously sought in connection with the committee's Russian Federation investigation", the GOPs added.
