WASHINGTON (AP) — The Latest on testimony by the acting director of national intelligence and a whistleblower complaint (all times local):

9:05 a.m.

The intelligence whistleblower's complaint at the center of House Democrats' impeachment probe into President Donald Trump raises concerns about Trump lawyer Rudy Giuliani's role in seeking assistance from Ukraine to benefit the president's 2020 reelection campaign.

The redacted and anonymous complaint was released Thursday by the House intelligence committee.

The complaint suggests that Ukrainian leadership was "led to believe" that a phone call between Trump and Ukrainian President Volodymyr Zelenskiy was conditioned on whether Zelenskiy "showed willingness to 'play ball'" on issues raised by Giuliani.

Giuliani had publicly stated his intention to secure from Ukraine derogatory information about former Vice President Joe Biden and his son Hunter.

The complaint also details concerns from U.S. officials about "Giuliani's circumvention of national security decisionmaking processes."

In the days following the phone call between President Donald Trump and Ukraine's new president, senior White House officials intervened to "lock down" all records of the call. That's according to a declassified whistleblower complaint released Thursday by the House Intelligence Committee.

The complaint says that the whistleblower learned about the effort from "multiple U.S. officials."

Committee members are hearing testimony Thursday on the complaint and details of the July 25 call on which Trump prodded Ukraine's leader to work with Trump's personal lawyer Rudy Giuliani and the U.S. attorney general to investigate Democratic political rival Joe Biden.

Trump has said he's done nothing wrong. House Speaker Nancy Pelosi announced a formal impeachment inquiry.

Acting Director of National Intelligence Joseph Maguire is set to speak publicly for the first time about a secret whistleblower complaint involving President Donald Trump as House Democrats who have read the document say it is "deeply disturbing."

Maguire is not expected to reveal many details about the substance of the complaint when he testifies before the House intelligence committee Thursday morning, but House Democrats who are now mulling Trump's impeachment are hoping he will explain why he withheld it from Congress for weeks.

The complaint from an intelligence community whistleblower, the document at the center of a firestorm about Trump's handling of Ukraine, was made available to members of House and Senate intelligence committees Wednesday after Maguire had initially determined they couldn't see it.
