Wikileaks founder Julian Assange said Friday it is clear that President Obama would not have unveiled his new spying reforms had it not been for leaks by former NSA contractor Edward Snowden and whistleblowers before him.

The 42-year-old Australian told CNN it therefore doesn’t make any sense to talk about prosecuting Mr. Snowden without talking about charges against National Intelligence Director James Clapper, who last year told Congress that spying agencies did not “wittingly” collect mass troves of data on Americans.

As for the content Mr. Obama’s speech, Mr. Assange said he was not impressed.

“I think it’s embarrassing for a head of state to go on like that for 45 minutes and say almost nothing,” Mr. Assange told CNN.
