Baghdad , US President Joe Biden, on Monday, strongly criticized his Republican rival, Donald Trump, and described him as a 'convicted criminal' for the first time since the latter was convicted in a criminal trial of covering up the secret payment of money to a porn star, last week. "Guys, the campaign has entered uncharted territory. For the first time in American history, a former president and convicted felon is now seeking the presidency," Biden said during a fundraising campaign event in Connecticut. Biden added: 'Despite the concern this raises, what is most harmful is the comprehensive attack launched by Donald Trump on the American justice system.' Source: National Iraqi News Agency
