CNN’s 5 Things brings you the news you need to know every morning.

For the first time, more than 200 social media influencers received prime access to the Democratic National Convention this week. It marked an unprecedented effort by the Harris campaign to harness the power of content creators to reach more Americans — particularly young voters. Here’s what else you need to know to Get Up to Speed and On with Your Day. Vice President Kamala Harris made history Thursday when she accepted her party’s presidential nomination on the fourth and final night of the Democratic National Convention. Harris’ ascension makes her the first Black woman and first Asian American to lead a major-party ticket. In her keynote address, Harris evoked her experience as the eldest daughter of immigrants and vowed to be president for “all Americans,” while describing the November election as the “most important in the life of our nation.” Additionally, she promised a tax cut for the middle class, stronger border security and to restore reproductive rights. Her speech also cast former President Donald Trump as the enemy of classic American principles, pointing to Project 2025 as a blueprint of what he would do with a second term. The Supreme Court on Thursday blocked parts of an Arizona law that would enforce some proof-of-citizenship requirements for the November election. In a partial win for Republicans, proof of citizenship will be required for new voters in certain circumstances. However, voters who cannot document their citizenship status will still be allowed to register using a federal form. The Republican National Committee and GOP lawmakers had asked the high court to step into the clash over election rules in the state in a case that elevated non-citizen voting, an issue Republicans have tried to put front and center in this year’s campaign. Arizona is a critically important battleground in the 2024 presidential election: President Joe Biden carried the state by just over 10,000 votes in 2020. Former President Donald Trump won it in 2016. The FDA on Thursday signed off on updated Covid-19 vaccines as health officials warn of another summer wave of infections. Moderna and Pfizer said the updated mRNA shots will be available in pharmacies and clinics in the days ahead. “Given waning immunity of the population from previous exposure to the virus and from prior vaccination, we strongly encourage those who are eligible to consider receiving an updated COVID-19 vaccine to provide better protection against currently circulating variants,” said Dr. Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research. The prevalent strain in the US now is KP.3.1.1, estimated to account for 37% of cases over the past two weeks. That’s triple its level a month ago. A suspect arrested in Guatemala has been charged with helping to coordinate the 2022 smuggling attempt that ended in the deaths of 53 migrants in Texas. The Justice Department on Thursday said it will seek the extradition of Rigoberto Román Miranda Orozco, 47, who is charged with plotting the deadliest human smuggling operation across the US-Mexico border. Authorities said the smugglers were aware that their trailer’s air-conditioning unit was malfunctioning and would not blow cool air to the migrants trapped inside during the sweltering, three-hour ride from the border city of Laredo to San Antonio. When the trailer was opened in San Antonio, 48 migrants were already dead. Another 16 were taken to hospitals, where five more died. President Joe Biden called the tragedy “horrifying and heartbreaking.”
