If Trump wants to release another transcript, make him release the FULL thing
or he WILL redact/edit/manipulate it.
In fact, the Dems should subpoena the full transcript of the original MEMORANDUM "transcript" which was a highly redacted summary of the Ukrainian call, likely cutting out explicit references to quid pro quo. For weeks Trump and his supporters have either explicitly or implicitly represented the partial transcript as a full, word-for-word transcript which means, of course, the argument for subpoena is substantial.
An entire article in The New York Times (10.30.19) based on Lt. Col. Alexander S. Vindman's testimony makes this point directly:
"Lt. Col. Alexander S. Vindmanthe top Ukraine expert on the National
Security Council, told House impeachment investigators on Tuesday that
the White House transcript of a July call between President Trump and
Ukraines president omitted crucial words and phrases, and that his attempts
to include them failed, according to three people familiar with the testimony.
The omissions, Colonel Vindman said, included Mr. Trumps assertion that
there were recordings of former Vice President Joseph R. Biden Jr. discussing
Ukraine corruption, and an explicit mention by Ukraines president, Volodymyr
Zelensky, of Burisma Holdings, the energy company whose board employed
Mr. Bidens son Hunter."
But the President and his supporters have directly stated that the transcript we were given covered the entire call as reported by CNN:
. . . Trump himself has repeatedly insisted that the transcript released
by his White House was absolutely exact.
Twice in a press conference earlier this month, Trump went out of his way
to say the rough transcript was, in fact, a verbatim recounting of his call
with Zelensky. "I had a transcript done by very, very talented people --
word for word, comma for comma," said Trump at one point in that
early October news conference. "Done by people that do it for a living.
We had an exact transcript." Later, he added that the document was
an exact transcript of my call, done by very talented people that do this
-- exact, word for word.
