Amid the Biden administration's push to vaccinate all teachers by the end of this month. Our Mary Bruce tonight traveling with the first lady. Reporter: It may be his toughest challenge yet. President Biden now racing to fulfill his promise to reopen most schools by may. His new strategy, vaccite teachers as soon as possible. But our goal is to do everything we can to help every educator receive a shot this month, the month of March. Reporter: It's something many teacher unions have been demanding, even though the CDC says vaccinations are not a must for them to teach in person. Hi, everybody! Hi! Reporter: And today, the first lady stepping into this force debate, visiting schools that have successfully reopened. Biden says as a teacher herself, she gets it. I'm a teacher, I am teaching virtually and last week, I said to my students, hey, guys, how are you doing? And they said, Dr. B, we're doing okay, we're doing okay. But we can't wait to be back in the classroom. Reporter: According to one analysis, just 45% of K through 12 students in the U.S. Are attending in-person school every day. This Connecticut district Jill Biden visited is still a hybrid of online and in-person learning, and for parnltds like Emily, it's a juggling act. Have you had those days where you think, I just don't know how I'm going to do this? Every single day. You're questioning, are you doing more good than bad to your children? Are you doing what is going to actually make them thrive or are you hurting them? That's a tough question to answer every day. Reporter: High school history teacher Lauren is eager to get back to normal, but on one condition. What is it going to take to get there? Vaccines for every teacher. Reporter: You're saying the linchpin to this is getting teachers that vaccine. The CDC says that's not a prerequisite to having teachers back in the classroom. But they would feel more comfortable. Reporter: Mary Bruce is joining us from Connecticut, traveling with the first lady. And while we have you, Mary, the other major headline involving the president, about those $1,400 checks the president wants to send out to most Americans as part of his covid package, he's now made a compromise in order to get moderate democratic senators onboard with this plan, he can't afford to lose any of them? Reporter: David, the president has now agreed to limit who gets these checks. These $1,400 payments would now go only to Americans who make less than $8,000 a year or households earning less than $160,000 a year. It is a major concession from the president to get the support of the key moderate Democrats he needs to get his covid relief bill passed. David? Mary, thank you.
