The officials spoke on condition of anonymity to discuss personnel matters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Caldwell, who served in the Marine Corps, was one of several senior advisers who worked closely with Hegseth. Caldwell\u2019s ties to the secretary go back to Hegseth\u2019s time as the head of Concerned Veterans for America, a nonprofit that fell into financial difficulty during his time there. Caldwell worked at CVA beginning in 2013 as policy director and later as executive director.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">He also was the staff member designated as Hegseth\u2019s point person in the&nbsp;<a href=\"https:\/\/www.militarytimes.com\/news\/pentagon-congress\/2025\/03\/26\/obviously-classified-experts-say-hegseth-chat-leaks-invited-danger\/\" target=\"_blank\">Signal messaging chat<\/a>&nbsp;that top Trump administration national security officials, including Hegseth, used to convey plans for a military strike against Houthi militants in Yemen. The chat, set up by national security adviser Michael Waltz, included a number of top Cabinet members and&nbsp;<a href=\"https:\/\/www.militarytimes.com\/news\/pentagon-congress\/2025\/03\/24\/top-trump-officials-accidentally-shared-war-plans-with-media\/\" target=\"_blank\">came to light<\/a>&nbsp;because Jeffrey Goldberg, editor in chief of The Atlantic, was added to the group.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The officials did not disclose what leaks are being investigated, but there has been a crackdown across the Pentagon and the Trump administration on the disclosure of sensitive or classified information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Caldwell\u2019s ouster was first reported by Reuters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On March 21, Hegseth\u2019s chief of staff, Joe Kasper, said in a memo that the Pentagon was investigating what it said were&nbsp;<a href=\"https:\/\/media.defense.gov\/2025\/Mar\/21\/2003674265\/-1\/-1\/0\/EFFORTS-TO-COMBAT-UNAUTHORIZED-DISCLOSURES-OSD002809-25-RES-FINAL.PDF\" target=\"_blank\">leaks of national security information<\/a>. Defense Department personnel could face polygraphs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The memo referred to \u201crecent unauthorized disclosures\u201d but provided no details. Kasper warned that the investigation would begin immediately and result in a report to Hegseth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cI expect to be informed immediately if this effort results in information identifying a party responsible for an unauthorized disclosure, and that such information will be referred to the appropriate criminal law enforcement entity for criminal prosecution,\u201d Kasper said in the memo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Caldwell, who graduated from Arizona State University in 2011, also worked as a public policy adviser at Defense Priorities, a think tank based in Washington.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>Editor\u2019s note: This story has been updated.<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Officials said Caldwell\u2019s sudden downfall is tied to an ongoing investigation into unauthorized disclosure of department information.<\/p>\n","protected":false},"author":7,"featured_media":108972,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":19,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":[]},"categories":[160,36,19],"tags":[],"coauthors":[1417],"class_list":["post-48146","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-daily-news-roundup","category-newsletters","category-pentagon"],"acf":{"subheadline":"","legacy_arc_id":"AGHDOCIW5RD7NCTBP54HFGH4UU","arc_canonical_url":"\/news\/pentagon-congress\/2025\/04\/15\/pentagon-senior-adviser-dan-caldwell-ousted-in-probe-into-leaks\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Pentagon senior adviser Dan Caldwell ousted in probe into leaks - Defense News<\/title>\n<meta name=\"description\" content=\"Officials said Caldwell\u2019s sudden downfall is tied to an ongoing investigation into unauthorized disclosure of department information.\" \/>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Pentagon senior adviser Dan Caldwell ousted in probe into leaks\" \/>\n<meta property=\"og:description\" content=\"Officials said Caldwell\u2019s sudden downfall is tied to an ongoing investigation into unauthorized disclosure of department information.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/one.sightlinemg.com\/defensenews\/pentagon\/2025\/04\/15\/pentagon-senior-adviser-dan-caldwell-ousted-in-probe-into-leaks\/\" \/>\n<meta property=\"og:site_name\" content=\"Defense News\" \/>\n<meta property=\"article:published_time\" content=\"2025-04-15T22:15:08+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2026-08-08T16:23:43+00:00\" \/>\n<meta name=\"author\" content=\"Lolita C.
