Stimulus 2, or the Direct Payments Initiative, included in the stimulus bill HEALS, could reach 2 million more people than Stimulus 1, with the support of some Senate Republicans.

Marco Rubio (R-Fla.) and Tom Tillis (R-N.C.) are in favor of providing stimulus checks to 2 million U.S. citizens married to foreigners without Social Security numbers, Fox Business reports. Even if their incomes were below the IRS eligibility threshold, these individuals would not receive the $1,200 CARES Act stimulus checks.

"No American should be denied a federal stimulus check because they are married to a non-U.S. citizen alien," Rubio said in a statement.

"In the midst of a global pandemic, we must ensure that Americans receive the funds appropriated by the federal government to keep their families afloat during this national crisis.

According to The Hill, these 1.7 million citizens were shut out of the first round of stimulus checks at the direction of the White House. The second round of the stimulus package may be delayed as the White House turns against Rubio and Tillis.

With negotiations for the second round of the stimulus package underway, the parties involved in the talks may be trying to enhance their own interests. As a result, the schedule for the second round of the stimulus package is uncertain, even though the Senate is expected to release its proposal this week.

Whether or not Rubio and Tillis' proposal that co-filers married to aliens without Social Security numbers qualify for stimulus checks comes to fruition, millions of Americans will likely see a second stimulus check before the end of the year.

Although the Senate has not released a formal response to the House's "HEROES bill," Republican leaders have hinted to us what the framework for a second stimulus package might look like.

"We are talking about the same provisions as last time, so our proposal is exactly the same proposal as last time," said U.S. Treasury Secretary Steven Mnuchin, who is representing the White House in negotiations with lawmakers.

The last time was the first CARES Act, which designated $1,200 each for joint and several taxpayers earning less than $75,000 and $150,000 per year, and pro-rated up to $99,000 and $198,000 per year.
