U.S. Sen. Elizabeth Warren is being evaluated by Hillary Clinton's presidential campaign as a potential vice president, according to a report in The Boston Globe.

Warren, who would add a fiery, populist, liberal element to the ticket alongside Clinton's more reserved, centrist persona, endorsed Clinton earlier this month after extended speculation about her own presidential run.

In a related bulletin: An Associated Press report also lists Warren among two other Democrats, Virginia Sen. Tim Kaine and Secretary of Housing and Urban Development Julian Castro, as finalists for Clinton's running mate.
