I saw this in a letter from my state senator.

Problem:
The pronoun is incorrect.

Explanation:
The complete sentence was “The good news is that the ongoing Sunset Review of the Texas Department of Insurance is providing a unique opportunity for my colleagues and I to consider the role of the private insurance market in making health care available to Texans.” in a letter from Senator Rodney Ellis.

The correct pronoun for a “for” — F-O-R — phrase is “me”, not “I”.

For example, it is correct to say or write “a unique opportunity for me”.

Therefore, it is correct to say or write “a unique opportunity for my colleagues and me”.

The senator’s use of the pronoun “I” in “for my colleagues and I” is an example of hypercorrection.

The senator used “for my colleagues and I” as a substitute for “for my colleagues and me” because he erroneously overgeneralized from the correct use of “my colleagues and I” as the subject of a sentence.

Solution:
“… a unique opportunity for my colleagues and me …”
