(CNN) Florida Republican Rep. Dennis Ross is retiring after eight years of serving in the US House, citing the polarization in Washington as part of his decision.

"The polarization is a factor in it, but I also know that I wasn't going to do it for a career," Ross told CNN's Kate Bolduan in an interview Wednesday after announcing his decision he won't seek re-election.

"After eight years, it's time. It's been a great run. I've been very blessed. I'm not angry. I'm not upset with anybody," said Ross, who was elected in 2010, adding that it was always his plan to serve no more than 10 years.

The Florida Republican had made his announcement in a statement shortly after the Tampa Bay Times first reported he told his staff he was retiring.

"After thoughtful prayer and consideration, my wife Cindy and I decided that I will not seek re-election for a fifth-term in office," his statement read.
