About Secretary Esper

Dr. Mark T. Esper became the 27th Secretary of Defense in July 2019 when he was confirmed in an overwhelming 90-8 vote by the U.S. Senate in rare bipartisan fashion. Esper went on to successfully lead the Defense Department through an unprecedented time in the nation’s history: from conflict with Iran, an ongoing military campaign in Afghanistan, and counter-terrorist operations in the Middle East; to open competition with China and Russia amidst a fundamental shift in the geo-strategic environment; and from the greatest civil unrest and political turmoil America has seen in decades, to a major recession and the spread of a global pandemic the world had not experienced in over 100 years, all while dealing with an unpredictable White House.

I applaud Vice President Harris for committing to ask a Republican to serve in her cabinet. I hope former President Trump will do the same with a Democrat. Will show that both sides can work together, that bipartisanship is not dead, and will help heal the wounds after what promises to be a very close and contentious 2024 election. This should be a new norm for future administrations too. The American people want to see both parties working together to solve the problems and face the challenges facing them and our great country. Watch the interview Here .

President Biden should be lauded for providing arms and rallying the allies to defend Ukraine, but his reluctance to provide weapons when needed and later restrict their use has seriously hurt the war effort. Kyiv should be allowed to strike any non-strategic military targets in Russia. No more sanctuary for Putin.
