Ohio Gov. John Kasich (R) panned President Trump's tax plan for failing to include revenue increases to offset massive tax cuts, arguing that Republicans are abdicating their responsibility to protect against booming deficits.

“Somebody said something I found very interesting: When a Democrat is president, Republicans care about debt and Democrats don't. When a Republican is president, Democrats care about debt and Republicans don't," Kasich said Friday during a Washington panel hosted by The Christian Science Monitor.

"That’s how pathetic things get in this town."

Kasich, one of Trump's most outspoken rivals for the GOP presidential nomination, laughed when asked about the plan and noted that there are not enough details yet to consider the plan's effects.

While he agreed in principle with Republican orthodoxy that growth offered by tax cuts can create incentives to boost the economy, he warned against relying too heavily on the idea of "dynamic scoring" to justify deep tax cuts that aren't otherwise paid for.

Kasich specifically cited Republican Gov. Sam Brownback's Kansas, which had a budget that relied heavily on dynamic scoring and now faces "enormous revenue problems."

One major problem of those rising deficits, he added, is that they divert resources away from social programs for the poor. So he called on Congress and the White House to toe the line between tax relief and adding to the deficit.

“They need to be careful about adding an enormous amount of increase to the national debt," he said, "Because when the debt goes up, the jobs go down; and when the debt goes down, the jobs go up."

The Trump administration released a rough sketch of his tax plan on Wednesday in the form of a one-page overview. It includes lowering the top individual tax rate about 5 percentage points to 35 percent and slashing the corporate tax from 35 percent to 15 percent while eliminating many deductions.

But many in the GOP share Kasich's concerns specifically about the impact on the debt, and others question the lack of specific details within the plan.
