Sen. Bernie Sanders's (I-Vt.) campaign will spend $30 million on TV ads in the first four 2020 presidential voting states and California, The New York Times reported.

The newspaper noted that the announcement aligns Sanders, who has so far focused on a grassroots efforts, with more conventional campaign methods that could connect him with older voters.

"He brings regular people into the process who are not currently participating," Sanders adviser Jeff Weaver told the Times.

"You need to be reaching people in a nonpolitical space," he added. "To find people who are not going to caucus, you have to be in spaces where they are, and that's on television."

The ads will reportedly be developed within his campaign organization and shown in Iowa, Nevada, New Hampshire, South Carolina and California.

Sanders has appeared on television screens in Iowa since October, spending $1.3 million on ads in the state. On Thursday, his ads begin airing in New Hampshire, where he invested $1 million.

This development comes as two of his fellow 2020 candidates, Sen. Elizabeth Warren (D-Mass.) and South Bend, Ind., Mayor Pete Buttigieg, have opened more field offices in Iowa than the Vermont senator, the Times noted.

Sanders until now has instead focused on online campaigning.

The Vermont progressive has taken in the most money of the Democratic candidates so far, reporting he raised $61.5 million as of the end of September. The campaign has disclosed it has $33.7 million in the bank.
