Premise: In the United States Senate on Tuesday, Senators Byron Dorgan, a Democrat from North Dakota, and Mike Enzi, a Republican from Wyoming, introduced the "Freedom to Travel to Cuba Act" (S.428), a bill that would lift the travel restrictions that have prevented U.S. citizens from visiting Cuba since the early 1960s. The bill is co-sponsored by 20 senators, and the House of Representatives is considering a companion measure, H.R. 874, introduced by Representatives Bill Delahunt and Jeff Flake. The house measure has 121 cosponsors.
Hypothesis: the bill was co-sponsored by 19 senators.
