President Trump vowed tonight to protect Americans with pre-existing conditions, even though his administration’s actions say otherwise.

“The Democratic healthcare plan would obliterate Medicare and terminate Medicare Advantage for nearly half a million seniors here in Wisconsin,” he said, vowing that “Republicans want to protect Medicare.”

“Republicans will always protect Americans with pre-existing conditions, 100%," he added.

Trump also railed against Obamacare, and said “essentially, we’ve dismantled it.”

“It’s been brought down to size — if you’ve noticed your premiums are going up. They’re going up very little by comparison” to how much they would have gone up if Obamacare provisions had stayed in place, he said.

Why this matters: A Democratic measure aimed at eliminating short-term health care plans that don't have to cover pre-existing conditions failed in the Senate earlier this month. Maine Sen. Susan Collins was the sole Republican to vote for the measure. The resolution was aimed at rebuffing a Trump executive order unveiled in August that made it easier to buy these plans.

The White House supported several Obamacare repeal bills, including one in the House of Representatives that advocates argued weakened coverage of pre-existing conditions. Several moderate Republicans in the House of Representatives even cited a lack of protections for people with pre-existing conditions as a reason they voted "no."
