Trump instructed Pence not to attend the inauguration of Ukrainian President Volodymyr Zelensky in May — an event White House officials had pushed to put on the vice president’s calendar — when Ukraine’s new leader was seeking recognition and support from Washington, the officials said.
Months later, the president used Pence to tell Zelensky that U.S. aid was still being withheld while demanding more aggressive action on corruption, officials said. At that time — following Trump’s July 25 phone call with Zelenksy — the Ukrainians probably understood action on corruption to include the investigation of former vice president Joe Biden and his son Hunter Biden.
