On Tuesday's broadcast of MSNBC's "Andrea Mitchell Reports," Sen. Chris Van Hollen (D-MD) argued that border security is "something President Biden has pushed for for a long time, as well as immigration reform issues." But that linking that to Ukraine aid, "I fear, is going to mean that we don't get the Ukrainians the equipment they need, when they need it. We need to deal with both the issues, but tying them together in this way, I think has been harmful."
