WASHINGTON, Sept. 25 (Xinhua) -- U.S. Senate Intelligence Committee Chairman Richard Burr said Wednesday afternoon that the whistleblower complaint alleging President Donald Trump's inappropriate interactions with a foreign leader was just delivered to the committee, according to U.S. media reports.

CNN reported that Burr, a Republican, made the remarks as he headed for votes on Capitol Hill. He added that he had started reading the documents but didn't provide his initial impression.

The whistleblower complaint, filed by an unidentified intelligence official, alleged that Trump interacted inappropriately with a foreign leader and made an unspecified "promise."

The whistleblower complaint was filed with the inspector general of the intelligence community, an independent watchdog, but had previously been withheld by Acting Director of National Intelligence Joseph Maguire from Congress. Congressional committees probing the matter have demanded access to the whistleblower complaint.

Maguire and Michael Atkinson, the inspector general, are both expected to testify before the Senate Intelligence Committee later this week. Maguire is also is scheduled to appear before the House Intelligence Committee on Thursday, according to a report by The Hill.

Denying any wrongdoing, Trump said at a press conference in New York on Wednesday afternoon that he told House Republicans he fully supported transparency on the whistleblower information.
