Lady Gaga hits out at 'don't ask, don't tell' policy

Pop singer Lady Gaga has led a rally against the "don't ask, don't tell" policy that prevents openly-gay people serving in the US military.

Under the policy, which President Barack Obama has promised to repeal, gay people can serve, but face expulsion if they reveal their sexuality.

The star appeared at a rally in Portland, Maine.
