Republicans’ plan to sue Obama ‘is a stunt’

The US House of Representatives has approved a Republican plan to file a lawsuit against Barack Obama for allegedly exceeding his constitutional powers.

The lawsuit relates to the way the US president enforced the 2010 health care law.

Democrats say it is a campaign-year stunt designed to draw conservative voters to the polls in congressional elections in November. They also say it may be a prelude to an effort to impeach Obama, a suggestion which top Republicans say is groundless.
