Republican Wisconsin congressman Glenn Grothman says he’s still hopeful diplomacy can reduce tensions following a massive build-up of Russian troops near Ukraine’s border and fears of a possible invasion. Grothman says he also hopes the United States does not get involved in Ukraine too quickly. The U-S. Deputy Secretary of State says she does not know yet whether Russia is prepared to de-escalate the situation with Ukraine or if the Kremlin is serious about diplomacy.
