(CNN) Hillary Clinton held meetings in early February with former Vice President Joe Biden and Minnesota Sen. Amy Klobuchar to talk about the 2020 presidential election, a source close to the 2016 Democratic presidential nominee tells CNN.

The meetings happened at Clinton's home in Washington, DC, and focused on Biden and Klobuchar's possible 2020 bids. The meeting between Clinton and Klobuchar happened before the Minnesota Democrat announced her candidacy on February 10 in Minneapolis.

Biden is still considering a bid and is said to be moving closer to a decision on whether to run for president.

Spokespeople for Biden and Klobuchar both confirmed that the meetings occurred.
