Maryland Gov. Larry Hogan (R) wants Congress to revive the Affordable Care Act subsidy payments cut by President Trump even though he did not sign a letter sent by 10 Republican and Democratic governors on Wednesday encouraging lawmakers to do it, a spokesman said Thursday.

Communications Director Doug Mayer said the governor supports an effort by Sens. Lamar Alexander (R-Tenn.) and Patty Murray (D-Wash.) to renew the payments, which are made to insurers to help lower deductibles and out-of-pocket costs for lower-income people.

But Mayer said Hogan opted against signing the letter because the legislation could change.

"We certainly support a legislative fix and will support this legislation as it is written. . . . We believe it needs to be passed," Mayer said Thursday. "But in D.C., sometimes legislation starts off in one direction and ends up in a different direction. . . . We'll keep a close eye on it as it moves through the Senate."

Democrats, who continue to try to tie Hogan to Trump, hammered the governor for not adding his name to the letter, which included the signatures of Ohio Gov. John Kasich (R), Massachusetts Gov. Charlie Baker (R) and Virginia Gov. Terry McAuliffe (D).

Fabion Seaton, a spokesman for the state Democratic Party, said Hogan's refusal to sign the letter "reiterated his commitment to standing with Washington Republicans instead of the people of our state."

Mayer said the governor supports the legislative remedy and the current legislation.

"You never know what can happen with this piece of legislation," he said. "We have signed letters in the past with this group; in this case we decided not to."
