“You can’t trust this president to do the right thing,” chief House prosecutor Adam Schiff said in an emotional speech on the Senate floor on Monday at the end of the two-week trial, AFP reported.

“Truth matters little to him,” the California lawmaker told the 100 members of the Senate who will decide Trump’s fate. “What’s right matters even less and decency matters not at all.

“He will not change and you know it,” Schiff said of the former New York real estate tycoon turned politician. “Now do impartial justice and convict him.”

White House lawyers flatly rejected the arguments that Trump – just the third president in US history to be impeached by the House of Representatives – should be removed from office by the Senate for abuse of power and obstruction of Congress.

“The president has done nothing wrong,” White House counsel Pat Cipollone said, calling the impeachment by the Democratic-led House “purely partisan and political.”

“We put our faith in the Senate,” he said.

“End the era of impeachment once and for all,” Cipollone said, arguing that the American people – not the Senate – should decide whether Trump remains in office.

Jay Sekulow, another of Trump’s lawyers, said the House impeachment was “reckless” and urged the Senate to acquit.

“The bottom line is that the president’s opponents don’t like the president and they don’t like his policies,” Sekulow said.

The Senate is to vote at 4:00 pm (2100 GMT) on Wednesday and the Republican president is all but certain of being acquitted.

Republicans hold 53 seats in the Senate to 47 for the Democrats, but a two-thirds majority, or 67 senators, is needed to remove a president from office.

The House of Representatives impeached Trump on December 18 for withholding $391 million in military aid to Ukraine to demand that Kyiv open an investigation into his potential November election rival, Democrat Joe Biden.

Schiff urged senators to find “courage to stand up” to the president.

“When the president tries to coerce an ally to try to help him cheat in our elections and covers it up we must say enough,” he said. “He has compromised our elections and he will do so again.”

Colorado lawmaker Jason Crow, another House prosecutor, said impeachment was an “extraordinary remedy.”

“It is in the Constitution for a reason,” he said. “In America, nobody is above the law, even those elected president of the United States.”

Crow told the senators their votes would echo through history.

“What you decide on these articles will have lasting implications for the future of the presidency, not only for this president but for all future presidents,” he said.
