Today's sanction is a follow up to last week's announcement by the Trump administration in which the Treasuey revealed sanctions on 13 senior Venezuelan officials in an attempt to deter Maduro from moving forward with plan to rewrite Venezuela's constitution in what opponents regard as a potential power grab move. Needless to say, that particular attempt failed.
Today's escalation comes in response to this weekend's election which gives Venezuela's ruling party new, sweeping powers. State Department spokeswoman Heather Nauert charges the new assembly formed from this election "is designed to replace the legitimately elected National Assembly and undermine the Venezuelan people's right to self-determination."
