The U.S. House intelligence committee on Thursday released a redacted version of a whistleblower complaint at the centre of an impeachment probe against U.S. President Donald Trump.

The still-unnamed whistleblower, who filed the complaint on Aug. 12, said they were reporting an “urgent concern” regarding Trump’s behaviour while on a phone call with Ukrainian President Volodymyr Zelensky. 

“I am deeply concerned that the actions described below constitute ‘a serious or flagrant problem, abuse, or violation of law or executive order’ that ‘does not include differences of opinion concerning public policy matters,’ consistent with the definition of an ‘urgent concern,'” the report said.

The White House tried to “lock down” records of Trump’s call, the document says.

The complaint says the whistleblower learned about the effort from “multiple U.S. officials.” 

This is at least in part related to a July phone call between Trump and  Zelensky in which Trump prodded the Ukrainian president to investigate Democratic political rival Joe Biden. 

The White House released a rough transcript of that call Wednesday morning.
