U.S. Sen. Bob Casey (D-PA), talks to Old Forge Jr-Sr High School students and staff Friday, Jan. 30, 2015. Casey and U.S. Sen. Pat Toomey have teamed up to ask the Democratic National Committee to come to Philadelphia for the 2016 convention.

WASHINGTON — Pennsylvania's two senators are teaming up to urge the Democratic National Committee to pick Philadelphia for its 2016 convention.

In a letter Thursday, Democrat Bob Casey and Republican Pat Toomey tout the city to DNC Chairwoman Debbie Wasserman Schultz as the best choice. Philadelphia is competing against two other finalists, Columbus, Ohio, and New York City's Brooklyn borough, which are hoping to host their first convention.

The senators point to Philadelphia's significance as the birthplace of U.S. independence and its track record of hosting national conventions. The city was host to the 2000 Republican National Convention.

Wasserman Schultz and a team of DNC staff visited the three finalist cities last week and are sorting through logistical details before making a final decision. An announcement is expected in the coming days.
