U.S. Sen. Brian Schatz is touting the endorsement of another Senate colleague.
In a campaign fundraising email sent Tuesday, Schatz announced the endorsement of Iowa Democratic U.S. Sen. Tom Harkin, who's retiring at the end of his term.
A message from Harkin, shared by the campaign, said:
"Since he came to the Senate, Brian has continued to stand up for progressive causes. I've worked with him closely on a number of critical issues, from student loans to clean energy to raising the minimum wage, and I've seen what he can get done. I know how he will fight for our values, and I know how badly the Senate needs him in 2014."
Schatz, appointed to the seat last year, faces U.S. Rep. Colleen Hanabusa in the 2014 Democratic primary to finish the remaining two years in the term of the late U.S. Sen. Dan Inouye.
