WASHINGTON (Reuters) - The Republican-led U.S. House of Representatives on Friday approved a measure making the first move toward scrapping Obamacare, joining the Senate in instructing key committees to write legislation repealing the health insurance law. Eliminating Obamacare is a top priority of the Republican-majority Congress as well as President-elect Donald Trump, who has urged lawmakers to act quickly. The resolution passed on Friday instructs committees of the House and Senate to draft repeal legislation by a target date of Jan. 27. The resolution passed by a vote of 227 to 198.
