This is new. Emails between OMB and the Pentagon about Ukraine were released a while back, but heavily redacted. Now the unredacted versions the House has been requesting have been made public, and they are damning:

Unredacted Ukraine Documents

Seems OMB continually misunderstood the process and mischaracterized what was going on to hide the illegal acts of the President. Then tried to blame the Pentagon after they ignored Pentagon warnings repeatedly.
