Sen. Joe Manchin, D-W.Va., could not attend, but sent a letter that stated, "Nick is a problem solver. We need more of them in Washington."
Kanawha County Commission President Kent Carper, a Charleston lawyer, said later Monday afternoon, "Casey will be good for the 2nd Congressional District. He will be good for Kanawha County. He has always been good to work with.
"Nick Casey also supported us in saving Yeager Airport," Carper added, when some were trying to build a new airport in Lincoln County that would have closed down existing airports in Charleston and Huntington.
Casey said Tuesday afternoon that he appreciated the mix of people at Tuesday's announcement, and that he is "pleased at the opportunity to look after such a diverse district. We are all West Virginians."
"We have some real economic bright spots -- cities like Shepherdstown, Martinsburg and Charles Town. All places in our district need attention."
Larry Puccio, chairman of the state Democratic Party, expects other people to announce their candidacies for the congressional seat.
"Any time there is an open seat, I think we will see three or four people from each party in the race," Puccio said. "Any time there is no incumbent, other people jump in."
Puccio said he would support whichever Democratic candidate wins the May 2014 primary. But as head of the state's party, he cannot support any candidate in a contested primary.
Casey, who earned a bachelor's degree in accounting from the University of Kentucky and a law degree from West Virginia University, is a managing member of Lewis Glasser Casey & Rollins, a Charleston law firm.
Casey is a past president and current member of the West Virginia State Bar Association and treasurer-elect of the American Bar Association, which has more than 392,000 members.
As a lawyer, Casey had experience in business development, government relations and legislative lobbying, as well as real estate leasing and acquisitions.

Mary Frances, Casey's wife, and their two children, Erin and Anthony, also attended the event.
