“Serious” threat to national security in the USA: Biden demands clarification. House Intelligence Committee Chairman Mike Turner released a statement Wednesday saying his committee had "provided information about a serious threat" to all members of Congress.

The Republican did not specify what kind of threat it was, thereby giving rise to all sorts of speculation. US media such as ABC News and Politico have now reported that the threat is apparently related to Russia. According to the information, there are signs that Russia under ruler Vladimir Putin is pursuing a plan to transport a nuclear weapon into space.
