President Donald Trump on Monday remained undecided over whether he’d sign a bipartisan housing bill, saying shortly after the House speaker sent it to the White House that it was “so unimportant” compared with his efforts to secure a controversial overhaul of federal elections.

“Big deal,” Trump said sarcastically of the legislation. “It’s a yawn.”

Speaker Mike Johnson transmitted the housing affordability bill to the White House on Monday, according to a spokesperson for the Louisiana Republican, kicking off a 10-day countdown for the bill to become law, even if the president does not sign it.

A source familiar with the matter said Trump is unlikely to sign the bill, though they noted that “he could always have a change of heart.” The source said Trump will not veto the bill either — he’d simply allow it to become law after the 10 days.

The president’s continued reticence comes after he abruptly canceled a signing ceremony last week for the housing bill, vowing not to approve it until the Senate agreed to move on his federal elections overhaul bill, the “SAVE America Act.”
