Mark Zaid, the lawyer representing the person who previously warned about Donald Trump's talks with the President of Ukraine, says he now represents a second whistleblower. ABC News reports.

Zaid tells ABC News that it is buying another person from the US intelligence service. They should have first-hand information about the allegations already made against President Trump.

The second whistleblower should have already been heard by the intelligence service's General Inspector Michael Atkinson according to Mark Zaid.

The charges against Trump

Donald Trump has called the first complaint from the first whistleblower "completely misleading".

Trump is accused of asking Ukrainian President Volodymyr Zelensky to investigate rumors that Joe Biden had a role in stopping a lawsuit against the Ukrainian company Burisma in which the son of Biden previously held a board position.

The first revelations about Trump's talks with Zelenskyj are what made the Democrats now work to put the president before state law.
