Stephanie Grisham says it was a mistake to work for Trump

• Grisham — who stayed in her post with Melania Trump until the final weeks of the Trump administration, resigning on Jan. 6 — told ABC's "Good Morning America" that she regrets enabling a cultural of "casual dishonesty" at the White House.

What they're saying: Grisham told ABC's George Stephanopoulos' that Trump would be "the front-runner in the Republican Party" if he were to run in the 2024 GOP presidential primaries — as he's often hinted.

• She added that he's on a "revenge tour," targeting Republicans who voted against him in his impeachment trial over the Jan. 6 U.S. Capitol riot.
• "I want to just warn people that once he takes office if he were to win, he doesn't have to worry about re-election any more," Grisham said. "He will be about revenge, he will probably have some pretty draconian policies."

Of note: When asked by Stephanopoulos why she stayed at the White House until nearly the end, Grisham said it was a "fair" and "complicated question."

• Grisham said she entered the administration a Trump supporter but upon joining the West Wing "started to see what it was really like and I regretted that decision immediately."

The bottom line: "Was it a mistake to work for President Trump?" Stephanopoulos asked.

• "Yes," Grisham replied.
