White House spokesperson Josh Earnest told reporters on Monday that the US government was given a “heads up” by British law enforcement ahead of their nine-hour detention of David Miranda over the weekend, but he would not discuss whether or not electronic materials seized from the Brazilian national and partner of Guardian journalist Glenn Greenwald have yet been shared or made available to US authorities.

From the White House briefing room, Earnest said, “This is a decision that was made by the British government without the involvement – and not at the request – of the United States government. It is as simple as that.”

Earnest gave no indication that US authorities cautioned against such a move and would not speak to directly to questions about whether President Obama found Miranda’s detention “at all concerning.”

Watch the exchange:

Meanwhile, “newspaper editors, human rights lawyers and civil liberties campaigners” all came out against the authority under which Miranda was held, putting pressure on officials in the British government to come clean about how and why such an “unlawful” detention was allowed.

As The Guardian reports:

In addition, in his first series of interviews, Miranda himself told reporters that his detention under a British anti-terrorism law—one in which he was refused access to a lawyer, a language interpreter, or a phone call—was filled with threats veiled and not-so veiled.

“They were threatening me all the time and saying I would be put in jail if I didn’t co-operate,” said Miranda from Brazil in a phone interview with The Guardian’s Jonathan Watts. “They treated me like I was a criminal or someone about to attack the UK … It was exhausting and frustrating, but I knew I wasn’t doing anything wrong.”
