Donald Trump returned to the roots of his first impeachment when he suggested that aid to Ukraine should be conditioned on congressional investigations of President Joe Biden. The former president called for Republicans in Congress to hold back on more support for Ukraine until the White House cooperates with their probes into the business dealings of Mr Biden and his son Hunter Biden. The Saturday night tirade at a rally in Erie, Pennsylvania echoed the conduct that led to Mr Trump’s first of his two impeachments when he used military aid to pressure Ukrainian President Volodymyr Zelensky to open an investigation into then-candidate Biden in 2019. “Congress should refuse to authorize a single additional shipment of our depleted weapons stockpiles … to Ukraine until the FBI, DOJ and IRS hand over every scrap of evidence they have on the Biden Crime Family’s corrupt business dealings,” Mr Trump said on Saturday. Meanwhile, Mr Trump’s Super PAC Save America spent $40m on legal fees in the first six months of this year, according to The Washington Post.
