A movement to push Massachusetts Senator Elizabeth Warren to enter the presidential race will come to an end next week.

MoveOn.org and Democracy for America say the Run Warren Run movement will be suspended next Monday. The campaign began six months ago, though Warren has repeatedly insisted she isn’t running for president.

Organizers say the movement was successful in getting Democratic candidates in the race to focus on progressive issues such as income inequality.

U.S. Sen. Elizabeth Warren has written to federal regulators stating that she has nothing to do with a newly formed political organization urging her to run for president in 2016.

Lawyers for the first-term Massachusetts Democrat, who was elected in 2012, delivered a letter to the Federal Elections Commission on Friday stating that Warren "has not, and does not, explicitly or implicitly, authorize, endorse, or otherwise approve" of any activities by "Ready For Warren."
