ABC News' Teddy Davis and Mike Elmore Report: On a Clinton campaign conference call with reporters, Rep. Henry Cuellar, D-Texas, swiped one of Obama's Texas supporters for not being able to cite any of Barack Obama's legislative accomplishments while appearing Tuesday on MSNBC's "Hardball."
"We need to make sure that we understand who we are supporting and the reasons why we are supporting this individual," said Cuellar.
Watch Texas State Senator Kirk Watson's "Hardball" appearance here.
Cuellar was joined on the call by Clinton spokesman Howard Wolfson who said of Watson, Obama's stumped supporter: "The problem is not the senator's memory. The problem is that [Sen. Obama] is not offering a record of accomplishment as his reason for people to elect him president."
Cuellar praised Clinton's work as first lady on the children's health insurance program as well as her work as a senator on behalf of veterans and 9/11 families.
He also touted Clinton as someone who can work with people of different ideological stripes. Cuellar, who won the endorsement of the Club for Growth and supports full repeal of the estate tax, said "the beauty of Hillary Clinton" is that she will "not just be working with the liberal side."
"There are a lot of people who are trying to purify the Democratic Party," said Cuellar.
