The Wall Street Journal owes its readers — and the public — better.

The business broadsheet published and hyped a story Wednesday declaring that “behind closed doors,” President Joe Biden has shown “signs of slipping.” The story questioned Biden’s mental acuity, playing into a GOP-propelled narrative that the 81-year-old president lacks the fitness to hold the nation’s highest office.

But an examination of the report reveals a glaring problem: Most of the sources reporters Annie Linskey and Siobhan Hughes relied on were Republicans. In fact, buried in the story, the reporters themselves acknowledged that they had drawn their sweeping conclusion based on GOP sources who, obviously, have an incentive to make comments that will damage Biden’s candidacy.

“Most of those who said Biden performed poorly were Republicans, but some Democrats said that he showed his age in several of the exchanges,” Linskey and Hughes conceded. The duo also noted that they had spoken to sources in the administration “who found no fault” with the way Biden conducted himself in meetings for which they were present.
