Trump gives nod to Republican tax-credit proposal on Obamacare

U.S. President Donald Trump backed the use of tax credits to help people purchase health insurance in a speech to Congress on Tuesday, the first time he signaled support for a key component of House Republican proposals to replace Obamacare. Republicans, who control the White House and Congress, are united in their opposition to former Democratic President Barack Obama's signature 2010 healthcare law, but have so far failed to agree on the details of how to replace it.
