Donald Trump's transition team pushed back Tuesday on reports that his grown sons are involved in an inauguration weekend charity event offering packages that include private access to the president-elect.

Donald Trump Jr. and Eric Trump are listed as "honorary co-chairmen" for the "Opening Day 2017" event, which is seeking donations for unnamed "conservation charities," according to a draft event brochure obtained by TMZ. The Center for Public Integrity reported that the two Trump sons are listed as directors on a Texas nonprofit called the Opening Day Foundation, which is putting on the event and was created on Dec. 14.

However, Trump spokeswoman Hope Hicks said in a statement that the plans are "initial concepts that have not been approved or pursued by the Trump family." Trump's sons are "not involved in any capacity," she said.

Walter Kinzie, the chief executive of Texas event management company encore live, told Public Integrity that a nonprofit called the Opening Day Foundation hired it to run the event. But he told the outlet that the document TMZ acquired is not entirely accurate and that the Trump family members are not definitely participating.

The Trump Organization did not immediately respond to CNBC's request for comment, while Encore Live declined to comment to CNBC.

The brochure posted by TMZ touts several packages that range from $25,000 to $1 million. The most expensive "Bald Eagle" package lists "a private reception and photo opportunity for 16 guests" with the president-elect and a multiday hunting or fishing trip with his sons, among other perks. A $250,000 and $500,000 package also give a private reception with Trump for fewer people.

The reports come amid broader concerns about the Trump family blurring the lines between business and politics. Trump's two grown sons serve on his transition team, helping to shape the administration, and will continue to help run Trump businesses when their father takes office.

A charitable auction for a meeting with Trump's daughter Ivanka was also recently canceled after questions were raised about the ethics of offering access. The proceeds were supposed to go to the St. Jude's Children's Research Hospital.
