By 2013, Gillibrand had "skillfully aligned herself with causes with visible, moving human characters who have helped amplified her policy goals." For example, in campaigning for the repeal of the military's "don't ask, don't tell" policy, Gillibrand established a website with videos of gay and lesbian veterans telling their personal stories. She has been less deferential to Senate seniority protocols and more uncompromising in her positions – such as combating sexual assault in the military – than most freshman senators, traits which have sometimes caused friction with her Democratic colleagues. Republican Charles Grassley of Iowa has contrasted her approach with other New Yorkers of both parties, saying she is distinguished by "her determination and knowledge and willingness to sit down one on one with senators and explain what she is up to". Her fund-raising ability – almost $30 million from 2009 through 2013 – helped her become a mentor for female candidates nationwide during that period.
