AUSTIN, Texas -- A Texas state senator accused of sending sexually explicit text messages to a graduate student says he doesn't "condone sexual misconduct of any kind" following an investigation launched by the University of Texas.

  • Sen. Charles Schwertner accused of sending explicit texts to UT grad student
  • UT report says he didn't fully cooperate with investigators
  • Investigation concluded he didn't violate policies based on "available evidence"

A report released Tuesday by the university said Republican state Sen. Charles Schwertner didn't fully cooperate with investigators and blamed the messages on someone the lawmaker has refused to identify. The investigation concluded that Schwertner didn't violate university policies based on "available evidence."

Schwertner said the university closed the investigation because he didn't "send the offensive text messages in question." But the report says Schwertner prevented investigators from reaching a definitive conclusion and raised the possibility that an unknown person who claimed responsibility for the messages is "being untruthful or does not exist."

Schwertner was re-elected in November.
