MINNEAPOLIS --U.S. Rep. Rick Nolan says he plans to support presidential candidate Bernie Sanders at the Democratic National Convention in July.

In a statement, Nolan said he has considered a number of factors, including "the will" of Minnesota caucus attendees and particularly those in the state's 8th congressional district.

Nolan says Sanders' message and his authenticity appeals to him and to voters in Minnesota. U.S. Rep. Keith Ellison has also pledged his support for Sanders.

The congressman is a so-called superdelegate for the Democratic Party. Superdelgates are not bound by primary elections or caucuses and are free to vote as they wish at the national convention.

A bulk of party superdelegates have already committed to Clinton.
