After approval of the Journal, the Speaker recognizes a designated Member to lead the House in the Pledge of Allegiance to the American flag. The Member designated alternates between the Majority and Minority party on a daily basis. The Member is usually informed in advance if he or she is the designated Member.

I pledge allegiance to the flag of the United States of America and to the Republic for which it stands, one nation under God, indivisible, with liberty and justice for all.
