Former basketball star and de facto diplomat Dennis Rodman will travel to Singapore next week for a summit between North Korea and the United States, and a cryptocurrency company that lets you buy marijuana is footing the bill.

"Thanks to my loyal sponsors from @potcoin and my team at @Prince_Mrketing, I will be flying to Singapore for the historical Summit," Rodman wrote on Twitter Friday. "I'll give whatever support is needed to my friends, @realDonaldTrump and Marshall Kim Jong Un."

Rodman's team at Prince Marketing Group confirmed the trip to CNBC. The Washington Post first reported his interest in attending the summit Thursday, and Rodman's agent told reporters he would provide "moral support" to President Donald Trump and Kim Jong Un.

The former Chicago Bulls player's past trips to North Korea have been paid for by the cryptocurrency company. During his 2017 trip, Rodman was photographed wearing a PotCoin T-shirt and baseball cap, sending the cryptocurrency up more than 90 percent from the previous day. It rose roughly 5 percent Thursday following the news, and was trading near 10 cents as of 11:30 am.m ET Friday, according to CoinMarketCap.com.

The U.S. has been pushing Pyongyang to abandon its nuclear programs, and the June 12 summit would mark the first time a sitting American president and North Korean leader meet face to face.

Rodman has been criticized for visits to North Korea in the past amidst the high political tension. In 2014, Rodman arranged a basketball game with other former NBA players and North Koreans, singing the North Korean dictator a rendition of "Happy Birthday."
