Based on my research, here is the fact-check for this claim:

Reasoning:

• Defense Secretary Pete Hegseth did dismiss senior Army generals on April 2, 2026, including Army Chief of Staff Gen. Randy George, Maj. Gen. William Green Jr. (Army chief of chaplains), and Gen. David Hodne (commander of Army Transformation and Training Command)¹²³.
• Senator Chris Murphy (D-CT), a member of the Senate Armed Services Committee, publicly criticized these dismissals in a statement⁴⁵⁶.
• Murphy stated: "It's likely that experienced generals are telling Hegseth his Iran war plans are unworkable, disastrous, and deadly" and added, "Also, Hegseth is firing a ton of experienced generals right now"⁵⁴.
• Murphy further criticized the timing of the firings, stating "Hegseth and Trump firing the highest ranking Army officer, in the middle of a war they started, shows you exactly where their priorities are"⁴.
