Trump Ordered Freeze of Ukraine Aid Ahead of Call Under Democratic Scrutiny VOA News U.S. President Donald Trump told his staff to withhold about $400 million in aid to Ukraine days before a phone call with the country's leader that is at the center of a debate between Congress and the White House over a whistleblower complaint. Reports late Wednesday from the Associated Press, Washington Post and New York Times all cited multiple senior administration officials saying Trump froze the funding, and that the order was communicated to the State Department and Pentagon with the explanation that he was looking into whether the money needed to be spent. Earlier Wednesday, the leaders of three House of Representatives committees demanded Secretary of State Mike Pompeo turn over all documents related to the call Trump made to Ukranian President Volodymyr Zelenskiy. The Democratic chairmen of the House Foreign Affairs, Intelligence, and Oversight committees -- Elliot Engel, Adam Schiff, and Elijah Cummings -- set a Thursday deadline, the same day the intelligence committee is set to hear testimony from acting director national intelligence Joseph Maguire about the whistleblower complaint linked to the call. Trump is said to have pushed for an investigation into leading Democratic presidential candidate Joe Biden and his son, Hunter, who served for years on the board of a Ukrainian gas company. The three House members said in their letter the State Department has admitted that a senior Pompeo staffer directly helped set up meetings between Trump's lawyer, Rudy Giuliani, and Ukrainian officials days after the call. "By withholding these documents and refusing to engage with the committees, the Trump Administration is obstructing Congress' oversight duty under the Constitution to protect our nation's democratic process," they wrote. Sen. Chris Murphy told reporters Monday that he met several weeks ago with Zelenskiy, and that the Ukranian administration worried the aid cutoff "was a consequence for their unwillingness, at the time, to investigate the Bidens." .
