"I served with Bernie. Almost everybody who has served with Bernie is supporting Hillary," she said on MSNBC inside a Nevada caucus site in Henderson. 
"You look at someone's achievement level and there's very little to show in terms of legislative achievement. I don't want to be snarky about it but the truth hurts. Hillary has accomplished a lot, both in the Senate and as secretary of State." 
Lofgren said she's backing Clinton despite the fact that she typically is on the side of the underdog candidate; she supported Howard Dean in 2004 and Barack ObamaBarack Hussein ObamaPatagonia files suit against Trump cuts to Utah monuments Former Dem Tenn. gov to launch Senate bid: report Eighth Franken accuser comes forward as Dems call for resignation MORE in 2008. 
The former chairwoman of the House Judiciary Committee's Subcommittee on Immigration and Border Security, she lamented that Sanders worked to scuttle immigration reform in 2007, an issue that Clinton campaign surrogates have repeatedly brought up to barb the Vermont senator. 
It's a vital issue in Saturday's Democratic Nevada caucuses, as Clinton looks to edge out Sanders's late surge in the state. Her campaign has relied on strong support from minority voters, which makes a state like Nevada with a substantial minority voter population a test of whether that support will hold. 
Sanders has repeated on the trail that he sided with Hispanic groups who believed the guest worker program in the bill amounted to "slavery." But the Clinton campaign blasted out his official 2007 statement on that bill to reporters, which doesn't mention that argument. 
Instead, Sanders's statement argued that the bill would have "driven down wages and benefits for U.S. workers by letting employers recruit lower-paid foreign guest workers." That prompted unions like the AFL-CIO to also express concerns that the bill would hurt labor. 
"Bernie did not stand with us," Lofgren said, "and we have never gotten that close again."
