Sen. Amy Klobuchar (D-Minn.) will open fundraisers for her presidential campaign to the press starting this week, her campaign said Tuesday.

Klobuchar’s announcement that she will allow the media to observe her fundraisers starting Wednesday comes amid heightened scrutiny over the entire primary field over transparency regarding their finances.

Sen. Cory Booker (D-N.J.) and South Bend, Ind. Mayor Pete Buttigieg, two other 2020 contenders, also recently announced that they would open their fundraising events to the press, while former Vice President Joe Biden has utilized a pool system for reporters for his fundraisers since the start of his campaign. 

Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.), the two leading progressives in the primary field, have eschewed private fundraising events in the name of transparency.

Klobuchar’s campaign will use a pool system similar to Biden’s in which it will allow for a single reporter to attend and cover fundraisers and then distribute a report at the end of the event. The campaign will also disclose its bundlers but gave no indications on the timing of that announcement. 

Klobuchar’s first fundraiser that will be open to the press will take place Wednesday in Los Angeles.

The push for candidates to open their fundraisers to the press began after Warren went after Buttigieg over his finances, saying he should disclose his clients from his time working for consulting firm McKinsey & Co., release a list of his bundlers and allow reporters into his private fundraising events.

The South Bend mayor has since disclosed his past clients and those who have raised over $25,000 for his campaign and announced he would allow media into his fundraisers.
