Poll: Americans equally concerned about Biden and Trump classified documents

By the numbers: 18% of respondents said they were not concerned with the discovery of documents at Biden's former office and Delaware residence, while 20% said they were not concerned with the Trump classified documents.

• 52% of Democrats said they're concerned about Biden's classified documents, while 53% said the same about Trump's documents, per NBC News.
• The poll was mostly conducted before revelations that documents with classified markings were discovered in former Vice President Mike Pence's home.

The big picture: An ABC News/Ipsos poll out last week also found that a majority of Americans said that both Trump and Biden acted inappropriately in their handling of the classified documents.

• The poll found that more Americans, 43%, said that Trump's handling of the documents "was a more serious concern."
