President Trump told Republican senators on Tuesday that a House-passed bill to repeal and replace Obamacare is "mean," and called for them improve the legislation so that it is more generous, a source familiar with Tuesday's White House meeting told the Washington Examiner.

Trump met Tuesday with 13 Republican senators, including some who are on a working group trying to find consensus on a healthcare reform plan.

Republicans praised the meeting upon returning to the Capitol, but most of them declined to talk in detail about what was discussed specifically.

The House bill, passed in May, would allow states to apply for waivers to escape Obamacare mandates and would allow health insurance companies to charge more for older people and for those with pre-existing conditions who have let their policies lapse. The bill would also cap Medicaid payments to the states, which would eventually result in reductions.

Trump praised the House-passed bill in a Rose Garden ceremony.

The Senate is now working it's own bill, and the Senate plan would likely phase out Obamacare expansion of Medicaid over several years. Lawmakers are grappling with how to deal with pre-existing conditions and who should receive tax credits.
