Congressional leaders, including House GOP leader Kevin McCarthy and Senate Majority Leader Mitch McConnell, will skip President Trump's departure ceremony in Maryland tomorrow morning in favor of attending mass with incoming President Joe Biden ahead of his inauguration, congressional sources familiar with their plans tell Axios.

Why it matters: Their decision is a clear sign of unity before Biden takes the oath of office.

What we're hearing: The Catholic service will take place at St. Matthew’s church in downtown Washington D.C., about 10 blocks from the White House. It is expected to begin at 8:45am, sources with direct knowledge tell Axios.

• Punchbowl News first reported details of the service.

Trump's sendoffwill be held at Joint Base Andrews at 8am on Wednesday. Trump requested a military-style sendoff with a band and possibly a flyover.
