US President Donald Trump has threatened whistleblowers in the affair for possible abuse of power "big consequences". In a series of tweets, the Republican wrote on Sunday evening (local time) that he wanted to face the anonymous whistleblower, who had launched a scandal that could lead to impeachment of Trump.

According to a media report, the whistleblower is under the protection of federal authorities. Against the informer from the secret service threats have been received, the broadcaster CBS reported on Sunday.

"Like any American, I deserve to meet my accuser," Trump tweeted. The whistleblower presented a "perfect conversation" with the President of Ukraine in a "completely inaccurate and fraudulent manner" and also presented "second-hand and third-hand information". He also wanted to meet the person who "passed on wrong information" to the whistleblower. "Did that person spy on the US president? Big consequences! "Trump tweeted.
