This claim that Kristi Noem approved the buying of several planes without engines for $200 million from Spirit Airlines is indeed a fact. Several reliable sources, such as The Wall Street Journal, the Senate website, and The Guardian, all state the same information regarding this purchase of planes. These organizations are known to be reputable, and confirmed what "MateoT" posted.
For primary sources, I went to the senate.gov website and found an article posted by Homeland Security and Government Affairs on October 24, 2025. It states that US Senator Gary Peters had sent a letter to DHS wanting to investigate her $200 million purchase of two luxury private jets. Noem has previously testified in Congress that she would only need $50 million to purchase 1 jet, and made no mention of multiple jets or any monetary value over $50 million, certainly not $200 million. Peters also went on to state that this $200 million was mainly paid for from taxpayers money, and that the current Trump Administration knows no limits in spending citizens' money. (https://www.hsgac.senate.gov/wp-content/uploads/SIGNEDLetter-to-DHS-IG-Re_-Noem-Jets2.pdf) This is a primary source of a letter sent by a senator to the DHS, so I know this is reputable since senators are under oath to tell the truth.
A secondary source that supports the claim made by MateoT is from the online newspaper company, The Guardian. An article by Mariana Dunbar, who is a reporter for The Guardian, goes into detail about the situation with the aircraft and shares a direct quote from a letter written by Democratic representative to the DHS about how the planes were purchased, "United States Coast Guard entered into a sole source contract with Gulfstream Aerospace Corporation to procure two new G700 luxury jets to support travel for you and the deputy secretary, at a cost to the taxpayer of $200m..." (https://democrats-appropriations.house.gov/sites/evo-subsites/democrats-appropriations.house.gov/files/evo-media-document/letter-to-noem.pdf) These direct quotes from those in power make the sources very reliable, and free from potential biases since these people apart of the government are sworn to an oath of truth. There would also be no agenda or reason for them to fabricate. However, biases and feelings surrounding the current political climate are very common nowadays, so one should definetely fact check from primary sources. before believing anything on either side.
