One-third of adults in a new survey indicated they don’t believe former President Trump had top secret and other classified material at his Mar-a-Lago estate this summer.

The Marquette Law School poll released Thursday found that 67 percent of respondents said that they believe he did have such documents, although the results varied widely among partisan groups.

Thirty-nine percent of Republicans said that they believe Trump had top secret and classified documents at Mar-a-Lago, compared to 65 percent of independents and 93 percent of Democrats.

The FBI executed a search warrant at Trump’s Florida property in August, saying agents retrieved some 33 boxes with roughly 100 classified documents.

Trump and his allies have accused the search of being politically motivated, and the former president told Fox News host Sean Hannity on Wednesday evening that he could declassify sensitive documents just “by thinking about it.”

Most adults in the new survey who expressed a favorable view of Trump, regardless of party, did not agree that he had secret documents in his possession, while 8 in 10 with an unfavorable opinion said that he did.
