(CNN) -- Justice Clarence Thomas and his wife, conservative activist Ginni Thomas, have gone on several luxury trips involving travel subsidized by and stays at properties owned by a GOP megadonor, according to a new bombshellProPublica report published Thursday.
The hospitality was not disclosed on Thomas' public financial filings with the Supreme Court, ProPublica said.
The report of the connection between Thomas and conservative businessman Harlan Crow is already adding to calls that Congress investigate potential ethical lapses. Key Senate Democrats were previously mulling using this year's funding legislation for the Supreme Court to pressure the justices to adopt some sort of ethics code.
The new ProPublica report describes Thomas accepting travel hospitality from Crow that included lavish trips to Indonesia, New Zealand, California, Texas and Georgia. Some of these trips reportedly included travel on Crow's super yacht or stays at properties owned by Crow or his company. ProPublica also identified what appear to be several trips taken by Thomas on Crow's private jet that went undisclosed on his public ethics filings, though one Thomas trip on Crow's jet was disclosed in 1997.
In a statement to ProPublica, Crow said that he been friends with Thomas and his wife Ginni for more than 30 years, and that the hospitality he has extended the justice over the years was "no different from the hospitality we have extended to our many other dear friends."
"Justice Thomas and Ginni never asked for any of this hospitality," Crow said in the statement. He said that we "never asked about a pending or lower court case, and Justice Thomas has never discussed one."
The Supreme Court and Crow did not immediately respond to a CNN request for comment, and ProPublica says Thomas did not respond to a list of detailed questions.
Thomas, nominated by former President George H.W. Bush in 1991, is the senior-most justice on the court and an intellectual leader of the current 6-3 conservative majority. The justice has also been the subject of scrutiny for the political activities of his wife, including for texts she exchanged with key players in former President Donald Trump's attempt to overturn the 2020 presidential election.
Crow, a Dallas businessman with deep connections to Republican politics, has contributed more than $10 million in publicly disclosed political contributions, ProPublica reported.
The ProPublica report documents a painting that hangs at the Crows' Adirondacks property depicting Thomas, Crow and other influential figures in Republican politics, including Leonard Leo, the former Federalist Society head who played a crucial role in Trump's makeover of the federal bench.
Executives of major corporations as well as heads of prominent conservative organizations have been in attendance on trips with Crow that Thomas has joined, the ProPublica report said.
"I am unaware of any of our friends ever lobbying or seeking to influence Justice Thomas on any case, and I would never invite anyone who I believe had any intention of doing that. These are gatherings of friends," Crow's statement to ProPublica said.
Thomas did disclose on his 2001 filings a $19,000 bible that belonged to Frederick Douglass that was gifted to him by the Crow family. ProPublica describes a portrait of the justice and his wife given to him by Crow as well as donation by Crow's foundation of $105,000 for a "Justice Thomas Portrait Fund" at Yale Law School, where Thomas is an alumnus.
Crow, in his statement to ProPublica, acknowledged that he has made "contributions to projects celebrating the life and legacy of Justice Thomas, just as we have done with other great leaders and historically significant figures." He said that neither Thomas nor his wife asked for those contributions.
The report comes not long after the federal judiciary's policy-making body quietly adjusted its interpretation of what justices are required to disclose as part of their gifts and hospitality transparency obligations.
