July 10 (UPI) -- Joe Biden has only seen a neurologist as part of his annual physical examination, the president's physician said late Monday in an attempt to squash swirling speculation about the commander and chief's health following reports stating an expert in Parkinson's disease made several visits to the White House this year.

"President Biden has not seen a neurologist outside of his annual physical," Kevin O'Connor, physician to the president, said in a letter released by the White House late Monday.

Concerns about Biden's mental and physical health were recently reignited following his debate last month that has some Democrats calling for him to exit the presidential race.

Those concerns where then inflamed Monday following reports from The New York Times and The New York Post on publicly available White House visitors logs that show Dr. Kevin Cannard, the Walter Reed National Military Medical Center's expert in Parkinson's, visited the White House three times this year and eight times in eight months.

White House press secretary Karine Jean-Pierre attempted to address the issue during a contentious press conference held earlier Monday.
