The House of Representatives is voting on the resolution formalizing the impeachment probe.
The vote will mark a significant step in the ongoing inquiry and it could prove to be a difficult political calculation for moderate lawmakers in battleground districts, though most House Democrats are already on record in support of the inquiry.
The resolution provides the procedural details for how the House will move its impeachment inquiry into its next phase as it investigates a whistleblower complaint alleging that the President attempted to pressure Ukraine to interfere in the 2020 presidential election by investigating the family of his potential political rival, former Vice President Joe Biden.
The House Intelligence, Foreign Affairs and Oversight Committees have been holding a series of closed-door interviewswith current and former administration officials as part of the inquiry, a phase of the probe that is still ongoing and has already stretched over several weeks.
