In a recent interview on "Face the Nation," Senator Lindsey Graham expressed concerns about President Joe Biden's capability to serve as commander in chief and called for neurological exams to be a mandatory part of the presidential candidate's overall physical examination. Graham's comments come amidst a debate surrounding Biden's mental and physical fitness for office.

Graham highlighted that a significant portion of the public shares his concerns, stating that approximately 70% of Americans believe that President Biden is not mentally and physically capable of leading the country. In addition, Graham raised worries about the implications of a compromised president on national security, as both allies and enemies may perceive Biden as weakened.

To address these concerns, Graham suggested that President Biden take a cognitive test, asserting that all future presidential contenders and individuals in the line of succession should also undergo neurological examinations. He emphasized the need to ensure that those who hold or aspire to hold the position of commander in chief can fulfill their duties under challenging circumstances.

Acknowledging the recent Supreme Court ruling on presidential immunity, Senator Graham was asked about former President Donald Trump's potential use of power if he were to serve a second term. Graham responded by anticipating that Trump would focus on pressing NATO members to meet their financial obligations, securing the border through executive action, and reversing policies implemented by the Biden administration.

Graham defended Trump's past performance as president, pointing to achievements such as achieving energy independence, fostering peace agreements in the Middle East, and maintaining a secure border. He expressed confidence in Trump's ability to enact effective policies if given the opportunity for a second term.

When questioned about Trump's recent social media posts suggesting televised military tribunals as a form of retribution against political opponents, Graham dismissed the idea, stating firmly that such tribunals would not occur. He maintained that the focus should be on policy debates and the need to change the current path of the country.

Regarding the topic of Trump's potential running mate for the 2024 presidential election, Graham expressed support for Senator Tim Scott from his home state of South Carolina. However, he emphasized the importance of choosing a vice presidential candidate who could add value and help expand the electoral map. Graham mentioned several names, including Governor Doug Burgum of North Dakota, author JD Vance, Senator Marco Rubio of Florida, and Glenn Younkin, a figure from Virginia, whom he believes could secure victory for the Republican Party in the crucial state.

As the 2024 presidential election looms, the call for mandatory neurological exams for presidential candidates gains traction. The debate surrounding President Biden's health and fitness for office continues to stir discussion, prompting lawmakers like Senator Lindsey Graham to advocate for ensuring the physical and mental wellbeing of future commanders in chief.
