House Democrats are trying to impeach U.S. President Donald Trump based on information they are so far keeping secret from the public.

The Democrat-led House Committees on Oversight and Reform, Intelligence, and Foreign Affairs pursuing the impeachment inquiry are refusing to release the full transcripts of the testimony provided by the first two witnesses.

Last week, former U.S. special envoy to Ukraine Kurt Volker and Intelligence Community (IC) Inspector General (IG) Michael Atkinson provided their testimony behind closed doors.

To the dismay of Republicans, witnesses expected to come to Capitol Hill this week are expected to follow suit.

Reps. Eliot Engel (D-NY), Adam Schiff (D-CA), and Elijah Cummings have chosen to release bits and pieces of the evidence gathered so far that favors their impeachment effort.

Engel, Schiff, and Cummings are the committee chairmen leading the impeachment investigation.

On Monday, Breitbart News reached out to the House panels for comment on when, if ever, they plan to release the full transcripts, but they refused to answer.

Irked by the Democrats’ refusal to release the full transcripts, Republican lawmakers who witnessed the testimony first hand and pundits have called for the information to be made public.

Via Twitter, Rep. Lee Zeldin (R-NY) on Saturday urged Democrats to release Volker’s testimony — which lasted more than eight hours — “so all can read it.”

“He candidly [and] professionally obliterated the bogus charge” by Democrats that President Trump made a quid pro quo offer to his Ukrainian counterpart, Volodymyr Zelensky.
