The Independent reported Thursday that House lawmakers are looking into a July phone call between Trump and Ukraine's new president, Volodymyr Zelensky, during which Trump allegedly pressured Zelensky to launch the probe.

Trump and his allies have been calling for months for an investigation into Biden's connections to Ukraine following a New York Times report detailing how the former vice president allegedly threatened to withhold $1 billion in U.S. loan guarantees in 2016 until Ukraine removed a prosecutor looking in to a company at which his son served as a board member.

The Washington Post first reported late Wednesday evening that a whistleblower had filed a complaint with the intelligence community's inspector general after Trump allegedly made a troubling "promise" to a foreign leader. 

Trump has dismissed the Post's report as "fake news."

"Virtually anytime I speak on the phone to a foreign leader, I understand that there may be many people listening from various U.S. agencies, not to mention those from the other country itself. No problem!" Trump tweeted Thursday morning.

"Knowing all of this, is anybody dumb enough to believe that I would say something inappropriate with a foreign leader while on such a potentially 'heavily populated' call," he continued. "I would only do what is right anyway, and only do good for the USA!"
