SALINAS, Calif. (AP) — Hillary Clinton is telling voters not to trust Donald Trump, but a new government report about her usage of a private server as secretary of state is complicating that message.

The sharp rebuke from the State Department’s Inspector General, which found Clinton did not seek legal approval for her homebrew email server, guarantees that the issue will remain alive and well for the likely Democratic presidential nominee.

The new report comes at a particularly challenging time for the Clinton campaign.

Already, Clinton faces questions about her trustworthiness, with months of polling showing voters give her low marks for integrity.

It’s a narrative that Trump has been eager to encourage. In the early weeks of his general election campaign, he’s dubbed Clinton “Crooked Hillary.”
