Today, Saturday, the US Senate begins listening to the defense team of President Donald Trump in the parliamentary trial on charges of abuse of power and obstruction of Congress, and is expected to take three days.

The prosecution team, headed by Speaker of the House Intelligence Committee Adam Schiff, has presented in the past three days to the House evidence of the charges against Trump.

Schiff said that Trump poses a threat to the United States, and that he cannot be trusted that he will resist any interference from Russia in the upcoming US elections, or that he will protect national interests at the expense of his personal interest.

"President Trump wants to be very strong, he is a dictator, and this should not continue," said Jerry Nadler, a member of the House of Representatives for the Democratic Party, speaking to the Senate.

During their pleadings, Democrats said that Trump withheld military aid and suspended a meeting at the White House to pressure Ukraine to investigate its political rival Joe Biden, to enhance the prospects of his re-election as President of the United States, adding that he then used his presidential authority to block Congressional investigation into the incident.

While Democrats have used nearly 24 hours for their opening arguments over three days, it appears that the president's defense team will operate faster, and during his arguments will confirm that an attempt to isolate Trump is unconstitutional and that the president has committed no wrongdoing.

In a related context, US Secretary of State Mike Pompeo heads to the end of the month for Ukraine, the country at the center of the president's trial, where he will meet in Kiev with President Volodymyr Zelenxy, who Democrats say was pressured by Trump to force him to help discredit Biden.
