Washington (CNN) A group of Republican senators on Sunday night released a version of President Donald Trump's immigration proposal ahead of a floor debate on immigration this week.

The proposal is expected to be one of several amendments the Senate will consider this week as it debates immigration. Senate Majority Leader Mitch McConnell has used a bill unrelated to immigration as the starting point for the debate, which will allow senators to offer proposals that can compete for 60 votes to advance.

At its base is still a resolution for the Deferred Action for Childhood Arrivals program, which has protected young undocumented immigrants brought to the US as children from deportation. Trump has decided to terminate the Obama-era program.

The White House proposal offered a pathway to citizenship for 1.8 million eligible immigrants, more than the 800,000 of whom registered for DACA in the five years of the program. In exchange, the White House sought upwards of $25 billion for border security and a wall, a number of changes to laws to make it easier to deport and detain immigrants, a substantial cut to legal immigration based on family relationships and an end to the diversity visa lottery.
