Donald Trump will showcase his vice presidential pick at a public event on Friday, multiple sources tell NBC News.

Trump's possible picks are thought to be narrowed to three candidates: Indiana Gov. Mike Pence, former House Speaker Newt Gingrich and New Jersey Gov. Chris Christie.

While the joint appearance is expected on Friday, it's not clear whether or not the identity of the pick could be released or could leak earlier in the week.

Trump is scheduled to attend a fundraiser and rally in Indiana Tuesday night with Pence; he campaigned with Christie on Monday and with Newt Gingrich last week.

He told the New York Times earlier Tuesday that he intended to make a decision "over the next three- to four-day period of time," adding that his "gut" would be an important factor in making the decision.
