WASHINGTON (AP) -- The Latest on President Donald Trump (all times local):

7:50 a.m.

White House advisers aren't backing away from President Donald Trump's claim that President Barack Obama wiretapped his campaign.

They insisted that Trump believes the explosive allegations he made over the weekend, for which he provided no evidence. The allegations were swiftly denied by an Obama spokesman and by Obama's intelligence chief.

Kellyanne Conway told "Fox & Friends" Monday that "credible news sources" suggested there was politically motivated activity during the campaign. She added that as president, Trump "has information and intelligence that the rest of us do not."

Likewise, Sarah Huckabee Sanders, deputy White House press secretary, told NBC's "Today" show that the president "firmly believes that the Obama administration may have tapped into the phones at Trump Tower."
