This isn't true. From the Impeachment Resolution, Article I, Abuse of Power
<< Using the powers of his high office, President Trump solicited the interference of a
foreign government, Ukraine, in the 2020 United States Presidential election. He did so
through a scheme or course of conduct that included soliciting the Government of Ukraine
to publicly announce investigations that would benefit his reelection, harm the election
prospects of a political opponent, and influence the 2020 United States Presidential election
to his advantage. >>
Under Article II, Obstruction of Congress:
<< President Trump abused the powers of his high office through the following means:
(1) Directing the White House to defy a lawful subpoena by withholding the
production of documents sought therein by the Committees.
(2) Directing other Executive Branch agencies and offices to defy lawful
subpoenas and withhold the production of documents and records from the
Committees—in response to which the Department of State, Office of Management
and Budget, Department of Energy, and Department of Defense refused to produce
a single document or record. >>
