Tea Party leader Mark Meckler on Thursday told The Hill he is “disgusted” by President Trump’s attacks on the conservative House Freedom Caucus over the GOP’s failed healthcare bill.

“The man who promised to ‘Drain the Swamp’ now appears to be the ‘Creature from the Black Lagoon,’ ” said Meckler, who co-founded the Tea Party Patriots and whose new group, Citizens for Self Governance, has a database of 2 million conservative activists.

“He is now on the side of the swamp monsters,” Meckler added.

Trump earlier Thursday issued a threat to the Freedom Caucus, warning them to “get on the team” or he would target them in the 2018 midterm elections.

Conservatives in the Freedom Caucus felt the bill did not go far enough, while some centrist Republicans opposed it as well.

Meckler and others on the right have warned that Trump risked losing his grassroots base by whipping support for the healthcare bill.

Many conservatives have so far directed their anger at Ryan and GOP leadership, who they say misled the president on the legislation.

But Trump’s attack on the Freedom Caucus could open up a rift with grassroots conservatives, who have defended the president against criticism over his support for the bill.
