Washington (dpa) - US President Donald Trump and his Republicans accuse the Democrats of artificially prolonging their opening speeches in the impeachment proceedings against Trump. The Democrats just kept repeating the "same old stuff" in the impeachment scam, Trump wrote on Twitter. Prosecutors and defense lawyers each have up to 24 hours over three days to present their arguments to the Congress Chamber. As of Saturday, the president's defense team will be on the line.
