Susan Rice was one Obama official who requested the unmasking of Trump associates' information that was widely disseminated. Here's why that's significant.
Since Donald Trump won the election for president in November, U.S. media outlets have received ad eagerly published selective, damaging leaks about him from anonymous intelligence officials. The general effort, which appeared highly coordinated, was to delegitimize Trump’s election and paint him as a stooge of Russia or otherwise unfit for office.
The media outlets claimed their information came from very highly placed officials in the Obama administration. Even if they hadn’t claimed their anonymous sources were Obama officials, the information they were leaking, such as the name of a U.S. citizen caught up in surveillance by the Obama administration, would have been known only by highly placed intelligence officials.
