The State Department did not immediately respond to a request for comment. Engel has been threatening to summon documents since May, when Johnson’s probe began to grow.
Johnson said a report on his findings could be released this summer, and his group is also trying to get testimony from national security and diplomatic officials at the Obama administration. He denied that his investigation was intended as a political freak or influenced by foreign interests that wanted to hurt Biden.
The chamber impressed President Donald Trump last year for urging Ukraine’s leaders to investigate Biden and other Democrats and to keep the country̵
Trump’s allies have responded by leveling off discredited allegations that Biden is pressuring Ukraine to fire a prosecutor investigating Burism, an energy company his son Hunter serves on board. During the impeachment proceedings, State Department officials testified that Biden’s work in Ukraine was carried out in accordance with the agency’s policy and that efforts to remove the prosecutor were part of an international push to eradicate corruption. They also noted that the prosecutor himself was an obstacle to the investigation of Burism.
Most recently, senior Democrats cited intelligence that suggests that at least some of the efforts against Biden are fueled by Kremlin-aligned Ukrainians who want to interfere in the 2020 election.
Spokesman Nancy Pelosi and Senate Democrat leader Chuck Schumer called for an FBI briefing for the entire intelligence congress, which they say shows a specific foreign conspiracy to influence Congress.
After attending a general election security briefing, Pelosi blew up the administration on Friday morning for “refusing” evidence of foreign interference.
