New York (CNN Business) Fresh off a campaign to get Amazon to raise its minimum wage, Senator Bernie Sanders is now shining his progressive spotlight on Walmart.

Sanders on Thursday introduced a bill, titled the Stop Walmart Act, that would prevent large companies from buying back stock unless they pay all employees at least $15 an hour, allow workers to earn up to seven days of paid sick leave and limit CEO compensation to no more than 150 times the median pay of all staffers.

Calling Walmart the poster child for corporate greed, Sanders noted that the company made $13 billion in profits last year and paid CEO Doug McMillon more than $22 million, or 1,188 times its typical worker, who earned $19,177.

Walmart, which this past February raised its minimum wage to $11 an hour, said it offers competitive wages and benefits, as well as the opportunity to advance and earn higher pay.

"We have increased our starting wages by more than 50% in the last three years and currently have an average hourly total compensation of more than $17.50 an hour," the company said in a statement. "At the same time, we've also added new benefits like paid time off, advanced job training, paid family leave and college for $1 a day."
