U.S. House impeachment inquiry to intensify; Trump remains defiant

The House of Representatives impeachment inquiry into President Donald Trump over his request that a foreign power investigate a domestic political rival is set to intensify this week with testimony due from witnesses concerning allegations made by a whistleblower within the U.S. intelligence community. The whistleblower’s complaint cited a July 25 telephone call in which Trump asked Ukrainian President Volodymyr Zelenskiy to investigate Joe Biden, one of the leading Democratic candidates seeking to challenge him in 2020, and his son Hunter, who sat on the board of a Ukrainian gas company.
