Sen. Amy Klobuchar promised DFLers in Pennsylvania for the Democratic National Convention this week, where Hillary Clinton will officially step up as the party's nominee, would set a far different tone than the Republican National Convention.

"What a contrast this is going to be with what we saw last week," Klobuchar said Monday morning at a breakfast meeting of the Minnesota delegation, which is staying in suburban Valley Forge, north of convention host Philadelphia.

Klobuchar noted a famous speech by the first Republican president, Abraham Lincoln, appealing to the "better angels" of the American people. "Donald Trump last week basically gave a 76-minute rebuttal," she said.

Minnesota's other U.S. senator, Sen. Al Franken, also slammed Trump's speech.

"Donald Trump painted a very dark picture of America," Franken said. "It's not an America I'm familiar with."

Both Klobuchar and Franken will speak this week at the convention being held at Philadelphia's Wells Fargo Center. Other Minnesotans speaking are Gov. Mark Dayton, U.S. Rep. Keith Ellison and state Rep. Peggy Flanagan from St. Louis Park. Ellison is also scheduled to speak Monday evening.

Monday night at the convention will feature speeches by Clinton's now-vanquished rival for the nomination, Vermont Sen. Bernie Sanders. The start of the convention has been clouded by the resignation of Democratic National Committee Chairwoman Debbie Wasserman Schultz after leaked emails showed her preference for Clinton over Sanders in the race; Minnesota's delegation is tilted toward Sanders after his win in the Minnesota caucus, and many of his supporters here were delighted that she quit.

Also speaking to delegates Monday morning was Jake Sullivan, a Minneapolis native and Southwest High graduate who is now a senior foreign policy advisor to Clinton's campaign.

Sullivan said the week's proceedings would be "an upbeat, big-hearted, confident convention -- the exact opposite of the terrible spectacle we saw last week."
