Just a week before the much-awaited book by President Donald Trump’s former National Security Advisor John Bolton is set to go on sale, the Trump administration is expected to file a lawsuit in federal court seeking an injunction to block the book from being released in its current form, sources familiar with the matter told ABC News.

The lawsuit is expected to be filed in the coming days and could come as soon as today, sources said, cautioning that some details are still being worked out.
