'Trump abused power of his office'

US President Donald Trump abused his power of office, a key Congressional committee from the Democratic-controlled House of Representatives has alleged in a report based on its impeachment hearings against the president.

"The evidence is clear that President Trump used the power of his office to pressure Ukraine into announcing investigations into his political rival, former Vice President Joe Biden, and a debunked conspiracy theory that it was Ukraine, not Russia, that interfered in the 2016 election," said chairs of the three House Committees after the release of a report on Tuesday.
