Perez said the United States' infrastructure systems have bridges and roads so old, if they were people, they would qualify for Medicare.
"The challenge that I see with that is when I look at what is being proposed, it's all about tax breaks," Perez said on "Squawk Box." "It's not an infrastructure bill."
The DNC chair said Friday infrastructure done right can be a "win-win."
The Trump administration said it would unveil a $1 trillion infrastructure plan later this year, which could offer incentives for public-private partnerships rather than simply fund improvements.
Democrats elected Perez, former President Barack Obama's Labor secretary, in February after a competitive race for chairman.
Perez has promised to rebuild state and local Democratic organizations that depend on the national party for support.
