“His threat may be bluster, but it’s also self-destructive,” the Journal’s editorial board wrote after the president renewed the feud on Fox Business. “Readers may have noticed this is becoming a presidential habit.”

Trump told Fox Business host Maria Bartiromo he’ll “have to fire him, OK? If he’s not leaving on time.”

“I’ve held back firing him. I’ve wanted to fire him, but I hate to be controversial,” the president said.

The Journal’s editorial board reacted to Trump’s remarks in the opening of its opinion piece, writing, “There he goes again.”

The opinion piece went on to bash the administration for manufacturing the “criminal probe with no evidence of criminal wrongdoing over the Fed renovation to bully Mr. Powell into stepping down.”

The board noted that firing Powell would only “invite a drawn-out legal fight that he might lose” and delay the confirmation of Kevin Warsh, the president’s pick to fill Powell’s position.

Warsh is scheduled for a Senate hearing next week but faces challenges for confirmation amid Powell’s criminal probe, which has drawn backlash from a handful of Republicans and which the Journal’s editorial board said is “backfiring in a big way.”

“Perhaps that’s what prompted his outburst in a Fox Business interview on Wednesday in which he doubled-down on his earlier threats to sack Mr. Powell,” the editorial board wrote.

President Donald Trump said he "wanted to fire" Federal Reserve Chair Jerome Powell, but he hates "to be controversial."

Sen. Thom Tillis (R-N.C.) told NBC News he will not vote to advance Warsh’s nomination until the DOJ drops the investigation, and Senate Majority Leader John Thune (R-S.D.) said, “it’s in everybody’s best interest to wrap up the investigation.”

“It’d be better if it winds down. A new man is nominated, very qualified. We’re excited, obviously, to get the opportunity to confirm him, but, you know, it would be great if we could wind up prior business before that happens,” Thune told the outlet.

Despite the challenges, Trump told Bartiromo he will not drop the probe.

“Mr. Trump might consider how his vendetta against Mr. Powell is complicating Mr. Warsh’s reform efforts at the Fed,” the editorial board wrote, noting that firing the chairman “won’t necessarily get the President what he wants.”
