MSNBC host Rachel Maddow said she has obtained part of Trump's 2005 tax forms and discussed the document on her Tuesday night show.

The records have become highly sought-after because Trump refused to release his returns during the campaign, breaking a decadeslong tradition. He claimed he was under audit by the Internal Revenue Service and said his attorneys had advised against it - though experts and IRS officials said such audits don't bar taxpayers from releasing their returns.

The White House says Trump made more than $150 million in income in 2005 and paid $38 million in income taxes that year.

Trump’s tax returns have been a sticking point for many people on either side of the political aisle.

Every president since Jimmy Carter has released his tax returns prior to the general election and a CNN poll in October found that 73 percent of registered voters wanted to see the documents.

MSNBC said David Cay Johnston received the tax filings in the mail.

The White House has not said whether or not the president plans to release his returns while he's in office. More than 1 million people have signed a White House petition urging the president to release them.
