Trump admin updates: Trump says tariff letters to be sent to 'various countries' on Monday

A procedural vote on the House floor that was set for five minutes has now been open for nearly an hour.

Currently, an amendment to the rule from Republican Rep. Virginia Foxx has 211 yes votes from Republicans and 212 no votes from Republicans, with nine "no votes" from Republican members.

The delay comes as several GOP hardliners have expressed unhappiness with the Senate-passed version of President Trump's sweeping domestic policy bill. House Speaker Mike Johnson was spotted by reporters walking off floor to his office around 2:30 p.m. ET. He was on the phone and avoided all questions from reporters.

Dr. Mehmet Oz, the administrator of the Centers for Medicare and Medicaid Services, was at the White House Wednesday during President Trump and Vice President Vance’s meeting with House Republicans, a source familiar with the matter told ABC News.

This meeting was with the "main street" Republicans concerned about the bill’s cuts to Medicaid, the source added.

Dr. Oz also had a call earlier this week with House Republicans who expressed concerns about funding cuts to hospitals, according to this source and another source familiar with the call. During that call, Dr. Oz mentioned that the Republicans should look into the finances of those hospitals, the sources said.

The Department of Health and Human Services did not immediately respond to a request for comment.

House Speaker Mike Johnson delivered "a progress report" to reporters on Wednesday afternoon -- stopping outside the chamber as he arrived for the rule vote as it remains unclear whether Republicans have the votes to keep the legislation on track for final passage.

"We are working through everybody's issues and making sure that we can secure this vote. I feel very positive about the progress," Johnson said after meeting with various factions within the House Republican Conference. "We've had lots of great conversations."

Johnson said that he and a "fully engaged" Trump have met with individuals and groups all day long "trying to convince everybody this very best product that we produce."

While Johnson said he feels "good" about the state of play, he hinted ominously, "there’s more conversation to be done."

The vote series is underway. The vote to adopt the rule to advance the Trump mega bill is the third vote in the series.
