The House on Monday expanded its sprawling impeachment inquiry, issuing subpoenas to the Defense Department and the Office of Management and Budget for documents that could solve lingering mysteries about whether President Trump’s decision to withhold security aid for Ukraine was tied to his efforts to pressure the government there to investigate his political rivals.
The action kicked off what was expected to be another busy week of investigation in Washington, where questions related to Ukraine appear increasingly likely to result in a vote on Mr. Trump’s impeachment.
