MINNEAPOLIS (AP) – President Donald Trump lashed out at potential Democratic presidential rival Joe Biden and his son Hunter. Trump said at a rally Thursday in Minneapolis that Biden became Barack Obama’s vice president because he knew how to curry favor with Obama. The Republican president also targeted Hunter Biden, suggesting a T-shirt that says “Where’s Hunter?” Trump has been spreading groundless claims that the Bidens used their family name to get China and Ukraine to pay them millions of dollars. The Democratic-controlled House opened an impeachment inquiry after a whistleblower complained about Trump’s dealings with Ukraine and alleged Trump was abusing his public office for personal political gain. Trump later released a rough transcript of a phone conversation with Ukraine’s president in which he asks for an investigation of Biden.
