Did TSA have the authority to mandate nationwide restrictions and mandates with regards to health-related issues

QUESTIONS PRESENTED . 1) The Transportation Security Administration “TSA” was created by Congress after the terrorist attacks on September 11 to protect the American people from SECURITY THREATS, and not for any health-related matters and/or pandemics. Congress chose not to enact a nationwide mask mandate for travel, yet the TSA enacted one. Did TSA have the authority to mandate nationwide restrictions and mandates with regards to health-related issues, that significantly affect almost every American? 2) Congress enacted the Air Carrier Access Act “ACAA” to protect the disabled while traveling by airplane. Can the TSA put the ACAA in abeyance and authorize and instruct airlines to implement policies that are in contrast to the ACAA regulations? Do they have this kind of power?
