Jill Biden to headline 2024 campaign events in New York, LA, San Francisco

First lady Jill Biden will headline several campaign events on her husband's behalf this summer, as he continues to face scrutiny over his age, health, and ability to serve as president.

Biden will appear at events in New York City, Los Angeles, and San Francisco, according to Fox News. In LA, she will participate in an event to celebrate the 30th anniversary of the pro-gun control Giffords Law Center, founded by former Arizona Rep. Gabby Giffords.

"As she has been for all her husband’s presidential campaigns, she will continue to be a formidable presence on the stump," said senior campaign adviser Elizabeth Alexander, per the outlet. "Her warmth and approachability, combined with her 30-plus years as a classroom teacher, make her an effective messenger on the campaign trail."

Nine years younger than her husband, the first lady is a veteran public speaker, but is not entirely immune to the Biden penchant for making awkward gaffes at public events. Last year, she drew criticism for a remark during a Texas event in which she called the Latino community "as unique as the breakfast tacos here in San Antonio."

More recently, Fox noted, she addressed an audience on Thursday for failing to clap after making a comment about common values that transcend political divisions, saying "I thought you might clap for that."

The first lady's prominence on the campaign trail, though not an uncommon event, could play into existing sentiment that the president himself is not up to the task of campaigning or leading the country. Former President Donald Trump famously branded his rival as "Hidin' Biden" in reference to his apparent unwillingness to appear at public campaign events.

It also comes as a majority of likely voters believe that Biden is not the one making the key decisions in the White House. A Rasmussen Reports survey in May showed that 55% of respondents believed Biden was not the driving force in the Oval Office. Seventy-three percent indicated that the president's age may present a problem for his reelection bid.
