Fred Guttenberg, a gun control activist whose daughter died during the 2018 Parkland mass shooting, has spoken about being ejected from the gallery during President Trump's State of the Union address Tuesday.

The big picture: Guttenberg, who was a guest of House Speaker Nancy Pelosi, was removed by security after yelling "What about my daughter!" as Trump spoke about protecting the Second Amendment, per Newsweek. Guttenberg tweeted that it was a "rough night."

What he's saying: "I disrupted the State Of The Union and was detained because I let my emotions get the best of me," he said in his Twitter post. "I simply want to be able to deal with the reality of gun violence and not have to listen to the lies about the 2A as happened tonight.

That said, I should not have yelled out. I am thankful for the overwhelming support that I am receiving. However, I do owe my family and friends an apology. I have tried to conduct myself with dignity throughout this process and I will do better as I pursue gun safety."

Ilhan Omar (D-Minn.) is facing a strong challenger as she fights for her political career. In Georgia, a Republican primary runoff pits a QAnon supporter against a hardline conservative.

The U.S. government has agreed to buy 100 million doses of Moderna's experimental coronavirus vaccine for $1.5 billion, or $15 per dose.

Why it matters: The Trump administration, through Operation Warp Speed, has now bought initial batches of vaccines from Moderna, GlaxoSmithKline and Sanofi, Pfizer, Novavax, Johnson & Johnson and AstraZeneca before knowing whether they are safe and effective. The federal government also appears to own some of the patent rights associated with Moderna's vaccine.

Democrats from across the party — including some of the women on Joe Biden's vice-presidential shortlist — are championing his historic appointment of Sen. Kamala Harris as his running mate.

What they're saying: "Joe Biden nailed this decision," former President Barack Obama wrote in a lengthy statement. "By choosing Senator Kamala Harris as America’s next vice president, he’s underscored his own judgment and character. Reality shows us that these attributes are not optional in a president."
