(CNN) - Russia's assurances that it has the Olympic security situation handled is not alleviating the worry among many in the U.S. government. Several lawmakers are expressing their anxiety ahead of the games.
"I would not go, and I don't think I would send my family," Sen. Angus King Jr., I-Maine, told CNN.
"We don't seem to be getting all of the information we need to protect our athletes in the games," said Republican Rep. Mike Rogers, chairman of the House intelligence committee.
So what will the U.S. government do if things go sideways in Sochi? CNN has learned of a contingency plan that involves putting as many as two warships and several large transport aircraft on standby. If the worst happens, they will be used to evacuate the thousands of American athletes, coaches, and officials in Sochi.
The plan calls for the warships to enter the Black Sea in the next few days.
"As far as the planning process, the U.S. government is confident at what its plans are that it can do," said former FBI crisis response agent Carl Herron, who was at the London Games in 2012 and in Turin, Italy for the 2006 games.
