The Southern Poverty Law Center more than doubled its revenue in 2017, in the latest indication that the Trump era has been a financial boon for the left-wing nonprofit.

The SPLC reported $136 million in contributions and grants for the most recent fiscal year, more than doubling the $50.2 million the nonprofit reported the previous year. The SPLC ended the year with $449 million in net assets, including a $432.7 million endowment.

The SPLC's financial portfolio includes off-shore investments in the Cayman Islands, British Virgin Islands and Bermuda, the organization's financial documents show.

The Capital Research Center, a conservative nonprofit, first noted the SPLC's impressive financial reports on Friday.

The center's senior vice president Matthew Vadum noted that "it would appear the SPLC is cashing in by generating unjustified fear over a handful of fringe-right groups and by falsely portraying President Trump as a racist would-be fascist dictator."

The SPLC did not return The Daily Caller News Foundation's request for comment.

The nonprofit's massive financial endowment invites "charges that it oversells the threats posed by Klansmen and neo-Nazis to keep donations flowing in from wealthy liberals," Ben Schreckinger noted in a Politico Magazine piece in June 2017. The SPLC's reported endowment increased $113.5 million since then, their most recent filings show.

Moreover, while the SPLC markets itself as a bulwark against white nationalists and the Klu Klux Klan, it has consistently mislabeled pedestrian conservative organizations as "hate groups," and critics of political correctness as "extremists."
