Trump nears likely acquittal as U.S. Senate to cast impeachment vote

Four months after Democrats in the U.S. House of Representatives launched a formal impeachment inquiry into President Donald Trump’s dealings with Ukraine, the Senate is poised on Wednesday to acquit him on charges of abuse of power and obstruction of Congress.

Trump, a Republican and only the third president in U.S. history to be impeached by the House and tried by the Senate, faces a 4 p.m. (2100 GMT) vote that will determine whether he can complete his term as president or must immediately turn over his office to Vice President Mike Pence.

It would take 67 of the 100 senators to oust the 45th president from office – an action that has never been taken by the Senate.

In 1999, Democratic President Bill Clinton was acquitted on charges of lying under oath and obstruction of justice stemming from a sexual relationship with a White House intern.

In 1868, President Andrew Johnson was found not guilty of 11 charges, which partially revolved around a post-Civil War tussle over his removal of the secretary of war.

Richard Nixon, the only president to resign, did so in 1974 when many of his fellow Republicans abandoned him during a House impeachment probe related to a break-in at Democratic Party offices in Washington.

If Trump is acquitted, Republicans and Democrats will take their respective cases to voters as Trump seeks re-election on Nov. 3.

Rancor amid the proceedings echoed in Congress late Tuesday as Trump delivered his annual State of the Union remarks, with tensions between the president and House Democrats spilling into public view.

Trump’s Senate trial, spanning 21 days, focused on whether he withheld U.S. aid to Ukraine last summer as leverage to get Kiev to launch an investigation of former Vice President Joe Biden, a Democratic contender in this year’s U.S. presidential election.

Trump denied any wrongdoing and Republicans in the House and Senate largely rallied around him.

But over the past few days, some Republican senators have criticized Trump’s behaviour, while defending his right to remain in office.

“It was wrong for him to ask a foreign country to investigate a political rival,” Sen. Susan Collins, a moderate Republican up for re-election this year, said on Tuesday, adding that Trump had learned his lesson.

Democratic Senator Chris-Van Hollen rejected that argument, telling CNN on Wednesday that “we know from the president’s own words that he has not,” as Democrats argue Trump will remain undeterred if faced with no rebuke.

Even with the outcome in sight, it remains to be seen whether any Democrats from Trump-leaning states break ranks to hand Trump a bipartisan acquittal.

Senator Mitt Romney, the only other moderate Republican along with Collins to go against the party earlier by urging more witness testimony, is also expected to make remarks on Wednesday.

Once the party’s standard-bearer as its 2012 presidential nominee, he has at times appeared out of step with a party now fully behind the president.

Senate Majority Leader Mitch McConnell, a Republican, has waged a vociferous defense of Trump on Tuesday, urging the Senate to “vote to keep factional fever from boiling over and scorching our republic.”

In response, Senate Democratic leader Chuck Schumer argued that it was “the beginning of the end of democracy” if Americans believe their elections are being manipulated through foreign interference, such as that solicited by Trump.
