Alabama U.S. Sen. Katie Britt will be among the list of expected Republican national lawmakers to speak during Monday’s action at the 2024 Republican National Convention in Milwaukee.

The convention opens in the shadow of Saturday’s attempt on the life of former President Donald Trump in Butler, Pa.

The presidential candidate was rushed off stage at a rally after he was struck in the ear by a bullet, the U.S. Secret Service said on Saturday. One person in the crowd was killed by the gunfire and two were critically injured. The shooter was killed by Secret Service personnel, authorities said.

“This is a moment for unity for the nation and a moment for prayer,” Britt told AL.com on Saturday. “It’s one of the darkest days in modern American history.”

“Political violence of any kind is completely unAmerican. It’s deplorable and unequivocally unacceptable. We have to remember we are one nation, under God. And we have to remember in moments like these, we must pray for the healing of this nation,” Britt said.

Britt heads a slate of Republican lawmakers scheduled to take the podium today, including several vice-presidential hopefuls for the Trump campaign.

Britt delivered the Republican response to President Joe Biden’s State of the Union earlier this year.

Trump is expected to announce his running mate at the convention, and speculation is increasing as to whom he will pick.

Ohio Sen. JD Vance, North Dakota Gov. Doug Burgum, and Florida Sen. Marco Rubio are among the names being discussed.
