Are we at War With Russia? If not, then what are these politicians talking about

Congressman Jason Crow, Nancy Pelosi, and Michael McCaul speak wrecklessly when talking about the War in Ukraine. Committing to standing with them till the end and give unending aid. They way they are speaking leaves one to conclude that we are also in war with Russia. How do you feel about what they are saying and do you think they should be more careful with the words they speak while the entire worked is watching?
