John Bolton decried Giuliani effort to pressure Ukraine as 'drug deal,' ex-aide Fiona Hill testifies, reports say

John Bolton called Guiliani a hand grenadeFormer national security adviser John Bolton wanted no part of what he derided as the White House's "drug deal" to pressure Ukraine into investigating Democratic presidential candidate Joe Biden, a former White House official told congressional investigators on Monday, according to reports of her testimony from The New York Times and NBC News.

Fiona Hill, who served as the National Security Council's senior director for Europe and Russia, spent more than 10 hours fielding questions from three House panels behind closed doors.

Her testimony was part of an impeachment inquiry into allegations President Donald Trump used military aid as leverage to get the Ukrainians to dig into an energy company that included the former vice president's son, Hunter Biden, on its board. Ukrainian officials have said they uncovered no evidence of wrongdoing on the part of the Bidens.
