Atlantic City - In a gesture to her former Democratic primary rival Bernie Sanders, Hillary Clinton is announcing new steps aimed at tackling the rising cost of college tuition and the burden of student loan debt, including a three-month moratorium on loan payments for all federal borrowers.Clinton is also calling for a plan that ensures families with annual incomes up to $125 000 pay no tuition at in-state public colleges and universities.Wednesday's policy roll-out is a direct overture to Sanders, the Vermont senator who posed a serious threat to Clinton in the Democratic primary and is yet to endorse her in the general election. A Clinton campaign fact sheet announcing the new proposals was laced with multiple references to Sanders and his calls for addressing college affordability.Sanders was wildly popular with young voters during the Democratic primary, with many drawn to his calls for free tuition at all public colleges and universities. Clinton cast her opponent's proposals as unrealistic, saying that while she shared his concerns about rising debt, she didn't want wealthier families to be able to take advantage of opportunities aimed at the middle and lower class.A centrepiece of Clinton's plan is an executive order that would give federal student loan borrowers a three-month break from making payments. During that window they would be able to consolidate their loans or sign up for other programmes aimed at reducing their monthly payments. Those who are delinquent or in default would get "additional rehabilitation options" the campaign said, though aides provided no details on those options.Clinton is also seeking to eliminate college tuition at public, in-state institutions for families making $125 000 or less per year. The campaign said the policy would roll out gradually, first for families making $85 000 or less and increasingly the threshold by $10 000 annually through 2021.The campaign did not provide details about how much the plan would cost or how Clinton proposes paying for it. It was unclear whether she would implement it using executive actions or need congressional approval.A third proposal from Clinton aims to restore year-round Pell Grant funding so students can receive financial aid for summer classes.
