FILE - In this March 26, 2013 file photo, Sen. Tom Carper, D-Del. speaks during a ceremony in New Castle, Del. at First State National Monument, which was designated a national monument by President Barack Obama. The House takes up a bill aimed at limiting President Barack Obama's ability to designate new national monuments. Obama created five new monuments last year, using executive authority to protect historic or ecologically significant sites. Republicans say the bill would not block new monuments, but would require greater public participation in such decisions. Seated behind Carper are, from left, Vice President Joe Biden, New Castle, Del. Mayor Donald Reese and Interior Secretary Ken Salazar. The monument is the first step toward creating a national park in Delaware, the only state not included in the national park system. (AP Photo/Patrick Semansky, File)
