US President Donald Trump continued to express his anger on the day after the Democrats launched his ouster, saying he was the most "abused" president in US history.

"No president has ever treated the United States as badly as I was," the Republican president wrote on Twitter from New York, where he is attending the UN General Assembly. Democrats are full of hatred and fear. ”

"No other president should be exposed to this, it's a hunt," he said, echoing the phrase he has repeatedly used to describe the special prosecutor Robert Mueller's investigation into Russian interference in the 2016 presidential election.

On Tuesday, Democrats launched the first phase of the indictment on suspicion of asking the Ukrainian president to investigate his potential rival in the 2020 presidential election, Joe Biden.

This resounding action is rarely triggered against an American president, but there are few chances of isolating Trump.
