I think Mineta's hand was in that.
Mineta also issued orders to screeners to not single out Arabs at airports about two days after 9-11.

Carrying Out Transportation Inspection and Safety Responsibilities
In A Nondiscriminatory Manner
http://airconsumer.ost.dot.gov/rules/20011012.htm
This is a reminder to Department of Transportation (DOT) employees and those carrying out transportation inspection and enforcement responsibilities
Do not subject persons or their property to inspection, search and/or detention solely because they appear to be Arab, Middle Eastern, Asian, and/or Muslim; or solely because they speak Arabic, Farsi, or another foreign language; or solely because they speak with an accent that may lead you to believe they are Arab, Middle Eastern, Asian, and/or Muslim.
Discriminating on the basis of national origin or religion includes discriminating against someone based solely on an appearance or dress that is associated with a particular national origin or religion. For example, selecting a woman for an inspection solely because her hair is covered or she is wearing a veil, as some Muslim women do, is illegal discrimination. Selecting a man for an inspection solely because he is wearing a long beard or hair covering, as some Muslim men do, is unlawful discrimination. Likewise, selecting a man for an inspection solely because he is wearing a turban, as some Sikh men do, is unlawful discrimination.
Be aware of inspection/search practices that might be offensive: during an inspection, asking a woman to remove her veil or hair covering may be offensive and could violate her religious tenets and asking a Sikh man to remove his turban could violate his religious tenets.
