President Trump on Wednesday canceled his trip to Gettysburg, Pennsylvania, where he was scheduled to join his personal lawyer Rudy Giuliani for a Republican-led state Senate Majority Policy Committee hearing on alleged election irregularities.

Driving the news: The cancellation comes after Giuliani was exposed to a second person who tested positive for the coronavirus. It's unclear if that's the reason the trip was cancelled.

• Trump campaign adviser Boris Epshteyn tweeted Wednesday morning he had tested positive for COVID-19.
• He attended a press conference last week with Giuliani, whose son Andrew also attended and later tested positive.

The big picture: Wednesday's hearing in Gettysburg comes just days after GSA ascertained the election results, formally signing off on a transition to President-elect Biden.

• State Sen. Doug Mastriano (R-Chambersburg) requested the meeting be convened to discuss reports he'd been told about "irregularities with the mail-in voting system and concerns whether their vote was counted."
• The president has yet to provide evidence to support his claims of widespread voter fraud.
• Pennsylvania officials certified the state's presidential election results on Tuesday, three days after a federal judge dismissed a Trump campaign lawsuit that sought to block the move and invalidate millions of votes in the state.
