Conservative radio host Lourdes Ubieta left Radio Mambi, an anti-communist station in Miami, which is one of the 18 stations a Soros-linked group will acquire in a $60 million deal later this year. The deal is still pending approval from the Federal Communications Commission.

"What I believe is this is about control and about politics," Ubieta argued on "Fox & Friends Weekend" Saturday. "And they are trying to silence the conservatives' voices, especially in Spanish."

The investment group Lakestar Finance, affiliated with Soros Fund Management, has partially funded the creation of Latino Media Network, a new network that will include Radio Mambi. The network and its stations are controlled by staunch Democrat supporters including a former Obama staffer and Clinton campaign employee.
