Senate Republicans are rejecting a request by moderate Democrats to jettison their party-line efforts on immigration and work on a bipartisan solution.

The U.S. Congress on Wednesday delivered Republican President Donald Trump legislation requiring the detention of immigrants living in the U.S. illegally who are accused of theft, with a significant number of Democrats voting in favor.

Mark Kelly of Arizona, sent a letter to Senate Majority Leader John Thune (R., S.D.) saying they are willing to provide the votes for legislation to address the country’s “pressing border security and immigration needs.

The House voted 263 to 156 to approve the Laken Riley act, sending the measure to Trump for his signature. The measure would make it easier for federal immigration officials to detain and deport those without legal status who are charged with specific crimes.

The senators said they would cooperate with the GOP to address "pressing border security and immigration needs”

Border state Sen. Mark Kelly (D-AZ) and a dozen other primarily Democratic senators are pushing the Republican-controlled Senate to include them in their work addressing the border and immigration matters.
