House Intelligence Committee Chairman Adam Schiff says Democrats will decide “in the coming days” what response is appropriate after hearing from a dozen witnesses in seven House impeachment hearings.

The seventh hearing began Thursday morning with witnesses Fiona Hill, a former White House national security aide, and David Holmes, a foreign service officer serving in Kyiv. Democrats are investigating President Donald Trump’s dealings in Ukraine as he pushed the country to investigate Democrats and withheld military aid.

Republicans have argued that Trump did nothing illegal. California Rep. Devin Nunes, the top Republican on the panel, said Thursday “marks the merciful end of this spectacle.”

A former White House national security adviser testifying before a House committee in an impeachment inquiry into President Donald Trump says that Russia and its proxies have geared up for 2020 election interference.

In prepared testimony, Fiona Hill cautioned against getting sidetracked by other narratives on election interference, as Republican members of the committee continue to push a debunked theory that Ukraine meddled in the 2016 presidential election.

Hill will tell lawmakers: “We are running out of time to stop them.”

The House committee is looking at whether Trump wrongly conditioned critical military aid for Ukraine on a public statement by their new president to look into the son of Trump’s potential Democratic rival Joe Biden and his ties to a Ukrainian gas company, as well as the 2016 elections.

A former National Security Council aide will tell the House impeachment hearing that one of the central Republican talking points — that Ukraine interfered in the 2016 U.S. election — is a “fictional narrative that has been perpetrated and propagated by the Russian security services.”

In prepared testimony Thursday, Fiona Hill stressed that she is a “nonpartisan foreign policy expert” who has served Republican and Democratic administrations. She says the conclusion by U.S. intelligence agencies that Russia interfered in the election “is beyond dispute.”

She adds, “I refuse to be part of an effort to legitimize an alternative narrative that the Ukrainian government is a U.S. adversary, and that Ukraine — not Russia — attacked us in 2016.”

Hill says the impact of the 2016 Russian campaign remains evident today. She says, “Our nation is being torn apart. Truth is questioned.”

Hill was a top aide to then-national security adviser John Bolton. She’s appearing before the House panel looking into President Donald Trump’s pressure on Ukraine to investigate Democrats and rival Joe Biden.

Hill says, “I have no interest in advancing the outcome of your inquiry in any particular direction, except toward the truth.”

Trump denies doing anything wrong.

A former White House national security aide will tell lawmakers they should not let domestic politics get in the way of defending against “foreign powers who truly wish us harm.”

Fiona Hill is a former official on the National Security Council who’s testifying Thursday before a House committee in the impeachment inquiry into President Donald Trump. Hill says in her prepared remarks that “if the president, or anyone else, impedes or subverts the national security of the United States in order to further domestic or political affairs,” it is worth the lawmakers’ attention.

But Hill says they cannot lose sight of the foreign powers, such as Russia, that truly wish to do harm to the United States.

Hill took aim at the lawmakers who do not believe Russia meddled in elections, telling them it was a “fictional narrative.”

Hill was an aide to former national security adviser John Bolton. She is testifying before a House panel looking into Trump’s pressure on Ukraine to investigate Democrats and political rival Joe Biden.

Trump has denied doing anything wrong.

House impeachment investigators will hear from two key witnesses Thursday who grew alarmed by how President Donald Trump and others in his orbit were conducting foreign policy in Ukraine.

David Holmes, a political counselor at the U.S. Embassy in Kyiv, says he was having lunch with Ambassador Gordon Sondland this summer when he heard Trump on the phone asking the envoy about the investigations he wanted from the Ukranian president. The colorful exchange was like nothing he had ever seen, Holmes said in an earlier closed-door deposition.

Fiona Hill says her National Security Council boss, John Bolton, cut short a meeting with visiting Ukrainians at the White House when Sondland started asking them about “investigations.”

The two witnesses set to appear Thursday are the last scheduled for public hearings.
