The House Intelligence Committee has released the transcript of the closed-door deposition at the impeachment inquiry into President Trump by a foreign service officer detailed to work in the office of Vice President Pence.

Jennifer Williams was assigned to Pence's team in the spring to work on European and Russian issues. She was the first person from his office to testify in the inquiry into whether Trump withheld military aid from Ukraine while seeking a political favor. Trump denies he made such an offer.

Marie Yovanovitch, the former U.S. ambassador to Ukraine, who was recalled in the spring amid what she previously described as a "concerted campaign" against her, told lawmakers Friday she did not understand Rudy Giuliani's "motives for attacking me."

Yovanovitch's remarks were part of an opening statement to the House Intelligence Committee in the impeachment inquiry into President Trump. Giuliani, the president's personal lawyer, has been named by other witnesses in the inquiry as pressing for Yovanovitch's removal.

The White House released Friday the rough transcript of the April 21 call between President Trump and Volodymyr Zelenskiy, the then-newly elected Ukrainian leader.

The 16-minute call was conducted from Air Force One and came three months before the July 25 conversation between the two men that prompted the impeachment inquiry into Trump.

In the April 21 call, Trump congratulates Zelenskiy, a political outsider, for the campaign he ran and invites him to the White House at an unspecified date.

William Taylor, acting U.S. ambassador to Ukraine, is presenting fresh information in the first public hearing of the impeachment inquiry into President Trump, telling lawmakers that Trump had asked Gordon Sondland, the U.S. ambassador to the European Union, about "the investigations" during a phone conversation that was witnessed by an aide to Taylor.

A senior State Department official testifying before the open-hearing phase of the impeachment inquiry into President Trump said Rudy Giuliani's "effort to gin up politically motivated investigations were ... infecting U.S. engagement with Ukraine."

The House has released the testimony of Catherine Croft, a Ukraine specialist with the State Department. The transcript is one of a number released ahead of the first public hearings of the impeachment inquiry into President Trump.

Foreign service officer Christopher Anderson's testimony has been released by Congress, as part of a new, public phase of the House impeachment inquiry into President Trump.

Anderson worked for U.S. envoy to Ukraine Kurt Volker and served as a special adviser for Ukraine negotiations from August 2017 through July 12, leaving days before a phone call between Trump and Ukrainian President Volodymyr Zelenskiy that helped trigger the inquiry.

House investigators have released the deposition of Fiona Hill, who until earlier this year served as the top Russia policy specialist on the National Security Council.

Hill was said to have told investigators that she registered concerns about President Trump's policy to pressure the government of Ukraine in exchange for commitments to launch investigations that might help him in the 2020 election.

House investigators have released the testimony of Lt. Col. Alexander Vindman, a top specialist on Ukraine on the National Security Council.

Vindman is an Army foreign area officer and is believed to have listened in to the July 25 call in which President Trump asked his Ukrainian counterpart for the "favor" that would have involved investigations that could help Trump in the 2020 election.

That makes Vindman a key witness in House Democrats' impeachment inquiry.

House investigators have released the deposition by Deputy Assistant Secretary of State George Kent, who talked behind closed doors about the Ukraine affair.

According to those who heard his testimony, Kent told investigators that the White House picked "three amigos" — diplomats Gordon Sondland and Kurt Volker, and Energy Secretary Rick Perry — to run Ukraine policy.

House investigators have released the deposition by William Taylor, who runs the U.S. diplomatic mission in the Ukrainian capital of Kyiv.

Taylor, a career foreign policy specialist in the State Department, has been a central witness in the Ukraine affair. He described the intent by President Trump, as described by another diplomat, to put Ukraine's president "in a public box" committing to investigations that Trump thought might help him in the 2020 elections.

House investigators released the transcript of former senior State Department adviser Michael McKinley's deposition on Monday.

McKinley, who was an aide to Secretary of State Mike Pompeo, stepped down because he said he objected to the practices within the administration in connection with the Ukraine affair.
