The Democratic president-elect has talked throughout the campaign and the post-election period about his goal of uniting a sharply divided country.

Biden’s incoming chief of staff, Ron Klain, on Tuesday retweeted a post that said Biden had quietly extended invitations to Democrats Nancy Pelosi and Chuck Schumer and to Republicans Mitch McConnell and Kevin McCarthy to accompany him to a Mass at St. Matthew’s Cathedral.

Spokespeople for Pelosi, Schumer, McConnell and McCarthy confirm they are accompanying Biden.

Sen. Chris Coons tells CNN the church service is “an important part of respecting tradition.”

Coons is a Democrat from Biden’s home state of Delaware. He says the service is a “reminder of who Joe is and who we are as a nation that’s hopeful and optimistic.”
