- While the outcome was never in doubt, supporters celebrated the victory of progressive state Senator Mark DeSaulnier to succeed longtime Congressman George Miller, who in 40 years in Congress, championed progressive positions on labor, education and environmental issues.
Congressional Progressive Caucus
The proposed Trans-Pacific Partnership trade deal "could only lead to the offshoring of U.S. jobs, especially in the service sector, and the erosion of America wages, nine newly-elected Democrats said in a letter to the president. Overall, 13 of 17 newly-elected Democrats are opposing Fast Track".
Rep. Ruben Gallego (D-AZ) led the efforts of a group of the letter writers and his version was signed by Brendan Boyle of Pennsylvania's 13th District; Mark DeSaulnier of California's 11th District; Debbie Dingell of Michigan's 12th District; Brenda Lawrence of Michigan's 14th District; Ted Lieu of California's 33rd District; Kathleen Rice of New York's 4th District; Mark Takai of Hawaii's 1st District; and Bonnie Watson Coleman of New Jersey's 12th District.
"[W]e believe this legislation lacked sufficient guarantees to ensure Congress' voice in shaping the substance of international trade agreements negotiated by the Administration," another group of freshman Democratic legislators wrote. "Our concern is that previous versions of TPA legislation did not ensure sufficient input of our constituents' concerns about labor, environmental, and human rights protections that must be essential in the trade deals you are currently negotiating."
Funding for Colombia
March 28, 2016 Washington, D.C. Rep. Ruben Gallego (D-AZ), Rep. Bradley Byrne (R-AL), and 14 of their House colleagues sent a letter to key House Appropriations Committee members asking them to fully fund President Barack Obama’s budget request for aid to Colombia.
Last month, President Obama announced a new aid package totaling $450 million for FY 2017 to assist the Colombian government in implementing a potential peace deal with the FARC guerillas after more than fifty years of violent conflict in the country. The funding would also support Colombia’s efforts to address security challenges including the threat of violent drug cartels.
“Now, just as the peace process is beginning to bear fruit, is not the time to reduce our financial assistance to our ally and partner,” the group wrote in a letter to Rep. Kay Granger (R-TX), chair of the House Appropriations Committee’s Subcommittee on State, Foreign Operations and Related Programs, and Rep. Nita Lowey (D-NY), who serves as the subcommittee’s ranking member. “After decades of equipping Colombia to fight, we have a vested interest in helping the Colombian people to rebuild. We must continue the robust, bipartisan support which, at long last, has brought Colombia to the precipice of peace.”
Signers include, Rep. James McGovern, Rep. Sam Farr, Rep. Hank Johnson, Rep. John Lewis, Rep. Linda Sanchez, Rep. Charles B. Rangel, Rep. Jim Himes, Rep. Eric Swalwell, Rep. Filemon Vela, Rep. Tony Cardenas, Rep. Dutch Ruppersberger, Rep. Mark DeSaulnier, Rep. Keith Ellison, and Rep. Mark Pocan.
“CAIR works hard to challenge Islamophobic rhetoric, mobilize the Muslim community and combatting the unprecedented spike in anti-Muslim hate incidents occurring nationwide. [. . .] I stand by the work done by CAIR in this regard.”
