Congressman Joel Hefley announces he will not seek an 11th term in the U.S. House of Representatives.
In a prepared news release, Hefley said he made the decision with mixed feelings.
"This decision has not been easy to make. I like my job and it is an enormous honor and privilege to represent the people of the 5th District of Colorado.
"I have received a great deal of encouragement to run again and I appreciate that support, but the timing seems right to move on to other opportunities."
Two people currently are running for his seat: Republican John Anderson and Democrat Jay Fawcett.
Colorado College Political Science Professor Robert Loevy says to expect more people to enter this race in the coming days and weeks.
Loevy said, "It means that those who wish to succeed him as the Fifth District Congressman are going to have to put their campaigns together very quickly, in a very hasty fashion."
Hefley wanted to remain in Congress until last year's round of base closures was completed and his term as chairman of the Defense Committee of the NATO Parliamentary Assembly was finished. That appointment ends in November.
