Two US Senators Republican Rob Portman of Ohio and Democrat Dick Durbin of Illinois announced the launching of Ukraine Senate Caucus designed to "strengthen the political, military, economic, and cultural relationship between the United States and Ukraine" on Monday.
The statement was made on the official website of one of its founders - US Senator Portman, Ukrinform's own US correspondent reported.
"The caucus will immediately focus on the need for a sustained U.S. commitment to Ukraine in the face of a Russian-backed separatist offensive," the statement noted.
U.S. Senators Kelly Ayotte (R-N.H.), Chris Murphy (D-Conn.), Sherrod Brown (D-Ohio) and Mark Kirk (R-Ill.) will serve as vice-chairs of the newly formed caucus.
The leaders of the caucus noted that the initiative for forming caucus in the upper house of the US Congress was made also possible, in particular, thanks to large Ukrainian-American communities in Ohio, Illinois and other states.
As earlier reported, Senators Durbin and Portman headed a group of 15 US Senators who demanded President Obama and NATO immediately expand their military assistance to Ukraine to defend its sovereign borders last week.
