The U.S. House of Representatives narrowly approved a bill to repeal Obamacare, handing Republican President Donald Trump a victory that could prove short-lived as the healthcare legislation heads into a likely tough battle in the Senate.

Republicans in the U.S. House of Representatives predicted victory in a planned voteto repeal Obamacare that would take a step toward achieving their seven-year quest to replace the healthcare law and hand President Donald Trump a major legislative victory.

President Donald Trump and his aides courted moderate Republican lawmakers on a proposal to overhaul the U.S. healthcare system as the White House struggled to avoid another embarrassing defeat on a top legislative priority.

Anthem Inc., which has 1.1 million customers in individual Obamacare plans, said it is moving ahead with its 2018 insurance filings but telling state regulators that it could increase premiums sharply and exit some markets.

The Trump administration issued a final rule that will shorten the Obamacare enrollment period and give insurers more of what they say they need in the individual insurance market, likely making it harder for some consumers to purchase insurance, healthcare experts said.

A U.S. House of Representatives panel met to consider a change to the stalled Republican healthcare bill before lawmakers leave for a two-week recess, a spokeswoman for the House Rules Committee said.

Republicans in the U.S. House of Representatives are considering a renewed push to pass legislation to repeal and replace Obamacare, lawmakers and aides said after the collapse of the effort last week.
