### House Republicans Subpoena Biden’s Doctor Amid Health Concerns

House Republicans have issued a subpoena to Kevin O'Connor, the former personal physician to President Biden, as part of their ongoing investigation into his health condition. This move underscores growing Republican scrutiny following new revelations about Biden's cognitive health in the recently released book, "Original Sin" by Alex Thompson and Jake Tapper.

James Comer (R-Ky.), chair of the House Oversight Committee, has escalated the investigation by compelling O'Connor to attend a deposition on June 27. Previously, O'Connor’s attorney had declined Comer's request for testimony, citing legal grounds including D.C. statute and the American Medical Association's code of ethics, as well as the principle of physician-patient privilege.

The Republican-led House Oversight Committee's actions highlight their intensified focus on Biden's age and capacity to serve, particularly in light of his recent cancer diagnosis. This investigation is also directing its efforts toward other key individuals in Biden’s circle, notably his former chief of staff Ron Klain and senior adviser Anita Dunn.

Senator Ron Johnson has also announced a separate probe into Biden’s health. This decision comes amid fresh GOP critiques following revelations that the White House may have concealed details of Biden's medical condition, questioning his overall ability to fulfill the responsibilities of the presidency.

The subpoenas and ongoing investigations illustrate the GOP's broader strategy to question Biden’s fitness for office as part of their political narrative, especially with the new insights brought to light by "Original Sin." The coming weeks are likely to see heightened tensions and focused debates as the detailed inquiries unfold.
