In July, nearly four months ago, Congress passed a set of sanctions against Russia.

They were intended to punish Russia for meddling in United States elections and its aggressive involvement in Ukraine. But the Trump Administration hasn’t implemented those sanctions yet.

That has observers wondering whether that delay is legitimate or whether the Trump campaign’s alleged ties to Russia have something to do with it?
