U.S. Senate Republicans are expected to issue a revised version of their healthcare bill on Monday, June 26 to address some of the concerns raised since it was unveiled last week, a Senate aide familiar with the plan said, according to Reuters.

The aide did not detail the revisions.

The bill has been criticized by some Republicans who say it does not go far enough in repealing former President Barack Obama's healthcare law, and others who say it would cut Medicaid too deeply.
