After the administration missed one congressionally-mandated deadline to implement new sanctions on specified Russian defense and intelligence entities, Senators are keeping a close eye on the next due date.

President Trump has been reluctant to implement sanctions. Senators John McCain (R-AZ), chairman of the Senate Armed Services Committee and Ben Cardin (D-MD), ranking member of the Senate Foreign Relations Committee, had little luck in getting the administration to answer for its actions last time around.

When lawmakers asked questions about the delay, they were left in the dark.

There is not much Congress can do to force Trump to act.
