US President Donald Trump appealed for "healing and reconciliation" Thursday following unprecedented scenes of violence at the US Capitol. Trump, who is under fire from all quarters, also pledged a smooth transition of power to President-elect Joe Biden. In a video message aiming to calm tensions after his supporters stormed the US Capitol as Biden's election victory was being certified by lawmakers Wednesday, Trump voiced outrage at the clashes that left one woman shot dead at the seat of US government.
