Coast Guard sounds alarm on Kristi Noem.

Homeland Security Secretary Kristi Noem’s relationship with the U.S. Coast Guard has become increasingly strained throughout her first year leading the department, according to two U.S. officials, a Coast Guard official and a former Coast Guard official.

Early in her tenure, Noem made decisions that rankled Coast Guard officials, including shifting resources away from a search-and-rescue mission to find a missing service member and putting them toward deporting migrants, the sources told NBC News.
