On October 31, 2019, voted to approve the rules governing the next steps in the impeachment inquiry. The resolution authorizes the US House of Representatives to begin public hearings and lays out the rules in which the House Judiciary Committee will follow during this inquiry, the vote passed 232 to 196. Two Democrats voted for the measure. Rep. Justin Amash (MI-I), who until this summer caucused with the Republicans, voted with the Democrats for passage of the resolutions. Three Republicans and one Democrat did not cast a vote.
Prior to Thursday, the House has only formally pursued impeachment just three other times: Andrew Johnson, Bill Clinton and Richard Nixon. Two, Johnson and Clinton, were impeached by the House but acquitted by the US Senate. President Nixon resigned prior to the Senate trial.
The resolution approved by the House, directs the House Intelligence Committee to hold public hearings and craft a report to be delivered to the Judiciary Committee. The Judiciary Committee would be responsible for drafting any eventual articles of impeachment.
The issue of impeachment is incredibly partisan and continues to amplify the divide between Trump supporters and non-supporters, according to recent research by Pew.
