Trump involved Pence in efforts to pressure Ukraine’s leader, though officials say vice president was unaware of allegations in whistleblower complaint

President Trump repeatedly involved Vice President Pence in efforts to exert pressure on the leader of Ukraine at a time when the president was using other channels to solicit information that he hoped would be damaging to a Democratic rival, current and former U.S. officials said.

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.
