The Texas claim is based on being a break way Republic from Mexico whose claim is based on Spanish exploration and settlement. Since Texas had no exploration of the area in question the Texas claim to lands along the north and eastern banks of the Rio Grande lack merit and standing. But that was all settled effectively in the 1850 compromise. The US did uphold the Texas claim to El Paso and in the County Club border settlement, the Supreme Court also sided against New Mexico.
Texas surrendered its claim to New Mexico; this was a bill to defuse the slave question (i.e: it had nothing to do with the country of Mexico, but between the U.S. North and South).
It was the other way around: at first, Mexico was owner of both Texas and California. Texas was lost on 1835, and then California, as well as some other territories, on 1848.
