Washington (CNN) Florida Republican Rep. Francis Rooney said Saturday he would not run for reelection, after suggesting he could be open to impeaching President Donald Trump.

"I've done what I came to do," Rooney told Fox News. He said he ran for Congress to "get the money for the Everglades projects that had been languishing for many years, and to try to get this offshore drilling ban passed to protect Florida."

Rooney, who won his first election in 2016, said he initially thought his goals would take three terms, "but I think I've done it in less than two."

Asked by Fox News if he needed or wanted to pursue a third term in office, Rooney said, "I don't really think I do, and I don't really think I want one."

The congressman said he wanted to be a "model for term limits," and added: "People need to realize ... this is public service not public life."
