WASHINGTON -- Attending the U.S. Embassy opening in Havana, Cuba on Friday, Sen. Amy Klobuchar said the last stage in fully cracking open diplomacy between the two countries is passing her bill to lift the Cuban trade embargo.

"Now it is time to continue moving forward by passing my bipartisan bill to lift the embargo, boost U.S. exports, and allow Cubans greater access to American goods," she said, in a statement.

Klobuchar attended the U.S. Embassy opening with Secretary of State John Kerry and Sens. Patrick Leahy, D-Vt., Jeff Flake, R-Az, and five House members. While in Havana, Klobuchar staffers say she will meet with Cuban government officials and business owners.

Klobuchar and Flake's bill currently has 21 co-sponsors in the U.S. Senate. If passed, the bill would allow the U.S. and Cuba to trade again and would also eliminate legal barriers to Americans doing business in Cuba.

Republican Rep. Tom Emmer is leading a Republican effort in the House on a measure to lift the Cuban embargo.
