Washington (CNN) Sen. Jeff Merkley released a document Tuesday showing a transfer of nearly $10 million from the Federal Emergency Management Agency to US Immigration and Customs Enforcement, and accused President Donald Trump's administration of diverting funds from hurricane relief just as hurricane season was starting.

However, the document from the Department of Homeland Security specifically mentions the money would come from the agency's budgets for travel, training, public engagement and information technology work. The department denies that the money came from disaster relief funding.

Merkley, a Democrat from Oregon, said on MSNBC's "Rachel Maddow Show" that the administration is taking money from "response and recovery" and "working hard to find funds for additional detention camps."

"I would dispute the statement that this has no bearing on ... addressing the challenges from hurricanes," Merkley said.
