U.S. Sen. Elizabeth Warren, D-Massachusetts, is among a handful of high-profile Democrats expected to speak at the Center for American Progress' upcoming Ideas Conference in Washington -- an event which some are billing as the progressive answer to the Conservative Political Action Conference.

The Massachusetts Democrat, who has become a favorite among the party's more progressive arm, will join fellow U.S. Sens. Chris Murphy, D-Connecticut; Cory Booker, D-New Jersey; Kamala Harris, D-California; and Kirsten Gillibrand, D-New York, in delivering remarks at the May 16 event, Politico reported.

The conference, which will offer a preview of sorts of possible Democratic presidential candidates in the 2020 cycle, is expected to be modeled somewhat after CPAC -- a popular stop for Republican leaders.

It comes as the Democratic Party looks to restructure and energize its base after a disappointing 2016 election.

With so much of the progressive organization's time focused on fighting President Donald Trump, CAP President Neera Tanden told Politico that it's critical for Democrats to offer a positive alternative of how they will address challenges facing the country.

"Ultimately, for 2018 and beyond we have to provide a positive alternative and we hope that this will be the beginning of that effort," Tanden reportedly said of efforts to make the sporadic symposium a major annual event.

Instead of focusing on political attacks, speakers have been urged to come up with proposals on issues like the economy, climate change, national security, civil rights, reproductive rights and immigration, Politico reported.

Warren, a high-power surrogate for 2016 Democratic presidential nominee Hillary Clinton, repeatedly sparred with Trump on the campaign trail.

Despite offering to work with the new president on areas of common interest after the election, the senator has remained outspoken against Trump.

The CAP Ideas Conference will take place at the St. Regis Hotel in Washington.
