Steve Rattner, a former Treasury Department official under the Obama administration, predicted Thursday that Americans wouldn't see the end of the inflation crisis anytime soon.

During an appearance on MSNBC's "Morning Joe," Rattner declared, "Inflation is here to stay," and argued it would be "the defining issue" in the upcoming midterm elections, making November "a really tough one" for Democrats.

FORMER OBAMA TREASURY ADVISER: BIDEN'S $1.9 TRILLION COVID BILL WAS ‘AN EXTRAORDINARY MISTAKE’

Co-host Mika Brzezinski began the topic by expressing her worry over inflation, as well as Democrats "hanging their hat" on being the solution to it.

"I’m not sure one person, one country, one party can solve this problem with everything that’s happening around the world," she said, before stating that President Biden had been traveling the country to learn from, and empathize with, Americans suffering from the crisis. She asked Rattner if inflation was "here to stay."

"Inflation is here to stay," Rattner declared, arguing it was "the defining issue in the midterm elections," and that the Democrats' control over the House and Senate was at stake because of it.

Referring to charts released by the Federal Reserve outlining the change in inflation rates over time, including a slight dip from March to April, Rattner suggested it was possible inflation might have peaked earlier in the spring.

He explained, however, that gas prices were having big impact on the inflation rate and pointed to them reaching record highs in March as inflation hit a 40-year high, but then dipped in April as the inflation rate saw a slight dip.

He added that if you removed gas prices from the calculation, the inflation rate for April would actually have been 0.4% higher than the massive 8.3% recorded rate.

"Look, the president has been blaming everything except himself and the Democrats for the inflation," Rattner said, arguing the only element in Biden's favor was that inflation is "a worldwide phenomenon."

He then outlined the factors contributing to inflation that he saw as within the control of the Biden administration.

"There is a fair amount of self-inflicted pain that we've put on ourselves with too much stimulus, too big budget deficits, too much bond buying by the Federal Reserve, too much money printing by the Federal Reserve, and that's what's coming home to roost," Rattner said. 

"And look, it's the number one issue, and it's going to be a really tough one for Democrats," he added.

He went on to argue that none of the policies being pushed by Biden would have "any meaningful affect" on inflation between now and the fall.
