WASHINGTON (AP) — Republicans are ready to muscle legislation through the House authorizing an election-year lawsuit against President Barack Obama that accuses him of exceeding his powers in enforcing his health care law. Republicans say the House's planned legal action is warranted because Obama has violated his constitutional duty to faithfully execute the laws. The lawsuit will focus on how Obama has carried out his health care overhaul, a 2010 law that is one of his most prized domestic achievements and that every GOP lawmaker opposed. The provision requires companies with 50 or more employees working at least 30 hours weekly to offer health care coverage or pay fines, while businesses with fewer than 50 workers are exempted.
