Does TSA or any airport security run your name for warrants when flying domestic?

Yes, the Transportation Security Administration (TSA) and airport security do check passenger names against various watchlists and databases, which may include information related to outstanding warrants. However, the specific processes and databases used can vary by airport and security protocols. It's important to note that while TSA screens for security threats, warrant checks are not the primary focus of their operations. If a match is found, further action may be taken by law enforcement.
