Obama defends Ann Romney amid row over motherhood

US President Barack Obama has defended Ann Romney, the wife of Republican presidential candidate Mitt Romney, saying there is "no tougher job" than being a mother.

Speaking to local news channel KCRG President Obama added that he did not have "a lot of patience" for comments directed at the families of presidential candidates.

The president's remarks come the day after a democratic strategist said Mrs Romney had "never worked a day in her life", triggering a political spat between the rival campaigns.
