Is John Fetterman's wife, Gisele, the 'de facto candidate' for Pennsylvania Senate?

Gisele Barreto Fetterman has been described as the "de facto" candidate as her husband, John Fetterman works to defeat his GOP challenger in the Pennsylvania Senate race.

Biden's comment comes at an inopportune time as political rivals and media outlets continue to speculate about the Democratic candidate's health and capacity to hold public office after a stroke took him off the campaign trail in May. But Gisele, who has been married to Fetterman for nearly 15 years, has emerged as one of his most ardent defenders. Kyle Morris covers politics for Fox News. On Twitter: @RealKyleMorris.

Rolling Stone reporter Kara Voght tweeted and deleted a post calling Gisele the "de facto candidate" for her husband's U.S. Senate campaign. Voght’s updated tweet changed the description of Mrs. Fetterman from "de facto candidate" to "key surrogate for her husband" in his campaign, seemingly to downplay the impression that John Fetterman is incapable of leading the campaign.
