House Speaker Nancy Pelosi said the impeachment hearing showed evidence of Trump bribing Ukraine to investigate political opponents.

"The testimony corroborated the evidence of bribery uncovered in the investigation. The president abused his power, violated his oath by threatening to stop providing military aid and canceling the White House meeting in return. investigation of his political opponent, "US House Speaker Nancy Pelosi yesterday told reporters after the first public hearing in the impeachment investigation of President Donald Trump.

Ms Pelosi confirmed the testimony at the hearing that the crimes of former president Richard Nixon, who resigned in 1974 to avoid impeachment, "look very small". "The military aid was used in exchange for a public statement or a fake investigation," the chairman of the US House of Representatives added.

Pelosi's statement showed that Democrats are changing words when describing allegations against Trump, using words like "bribery" instead of "exchanging interests" as before.

Americans on November 13 watched the first public hearing in Trump's impeachment investigation on television. Two witnesses, former US ambassador to Ukraine Bill Taylor and Deputy Assistant Secretary of State George Kent, revealed some new details regarding the alleged Trump urging Ukraine President Volodymyr Zelensky to investigate former Vice President Joe Biden, Trump's opponent in the race to the White House in 2020.

But experts say live testimony witnesses don't help prove the White House boss deserves impeachment, making it a Democratic defeat.

Republican lawmakers also spoke out in defense of Trump, saying that the two witness witnesses had never spoken directly to the White House boss about Ukraine.

There is nothing worth impeaching," minority leader in the US House of Representatives Kevin McCarthy said.

The next hearing will take place on November 15 in the presence of former US ambassador to Ukraine Marie Yovanovitch, who claimed to be dismissed because the Trump administration believes she will not support the plan to pressure Ukraine.

The Democratic-majority US House of Representatives announced an impeachment investigation into Trump in late September, after a "whistleblower" accused the White House boss of urging his Ukrainian counterpart to investigate the former vice president. Biden in a call on July 25. Biden is one of the leading candidates for the Democratic Party, Trump's rival in the race to the White House in 2020.
