As the weeks pass, concern continues to build over one of the most recognizable figures in American politics, with growing calls for more information about his condition and when—or if—he will return to public life.

Questions surrounding Sen. Mitch McConnell’s health intensified this week as his hospitalization stretched into another week, prompting renewed calls for his office to release additional information about his condition.McConnell, 84, has remained out of public view since he was admitted to a Washington-area hospital on June 14.

His office has provided only limited updates, most recently saying Monday that the Kentucky Republican “continues to improve” and remains engaged in Senate and Kentucky related matters while Congress is out of session

“The Senator continues to improve,” McConnell’s office said in a statement, adding that he appreciates the support and well wishes he has received during his recovery.The latest public photographs of McConnell were taken June 4, roughly 10 days before his hospitalization.

During that appearance, McConnell was photographed being assisted by two aides as he made his way through the Capitol to participate in Senate votes on a reconciliation package

It was one of several recent appearances in which the senator required assistance moving around the Capitol, including the use of a wheelchair.Two days later, on June 6, McConnell chaired a Senate Appropriations subcommittee hearing on President Trump’s military and defense strategy, marking his last known public appearance before entering the hospital.
