The legal team for Donald Trump have described the impeachment process against the US President as "irredeemably flawed" ahead of the trial's commencement in the Senate tomorrow.
The White House unveiled its legal defence today and argued that the Democrats have wrongly identified abuse of power as an impeachable offence.
They will also say there is no evidence to support the claims that the president threatened to withhold aid from Ukraine until it announced an investigation into Joe Biden's son.
Mr Trump's team say Democrats "do not have a single witness who claims, based on direct knowledge, that the resident ever actually imposed such a condition".
Included in Mr Trump's legal team is Alan Dershowitz who advised the defence team in OJ Simpson's murder trial and represented convicted paedophile Jeffrey Epstein.
He believes neither abuse of power nor obstruction of congress represent impeachable offences because there was no crime committed and only a court, not congress, should have the right to decide whether a president should release documents and make witnesses available.
He said: "The two articles of impeachment don't satisfy the constitutional criteria."
"The constitutional criteria are treason - nobody has alleged that he's committed treason; bribery - although there has been discussion of bribery, he wasn't charged with that; or other 'high crimes and misdemeanours'.
He said the argument rests on what he believes America's forefathers meant and intended when they wrote the constitution and "the law distinguishes between a sin and crime".
