With new Congress poised to convene, Obama's policies are in peril

Republicans plan to reserve the first 100 days of Congress for their more partisan goals

The most powerful and ambitious Republican-led Congress in 20 years will convene Tuesday, with plans to leave its mark on virtually every facet of American life — refashioning the country’s social safety net, wiping out scores of labour and environmental regulations and unraveling some of the most significant policy prescriptions put forward by the Obama administration.

Even before President-elect Donald J Trump is sworn in on January 20, giving their party full control of the government, Republicans plan quick action on several of their top priorities — most notably a measure to clear a path for the Affordable Care Act’s repeal.
