President Trump on Tuesday insisted there'll be "no cave" on his border wall demand.

President Trump on Tuesday insisted that, despite the lingering government shutdown, there will be "no cave" in his pursuit to get billions in funding for the wall along the US-Mexico border. He said in a tweet: "Without a Wall our Country can never have Border or National Security. With a powerful Wall or Steel Barrier, Crime Rates (and Drugs) will go substantially down all over the U.S. The Dems know this but want to play political games. Must finally be done correctly. No Cave!"  In his latest proposal to secure the $5.7 billion for the wall, Trump offered temporary, limited protections for undocumented immigrants who were illegally brought into the country as children.  House Speaker Nancy Pelosi turned down that proposal, calling it "a compilation of several previously rejected initiatives, each of which is unacceptable and in total, do not represent a good faith effort to restore certainty to people's lives."  While Trump has repeatedly attempted to place the blame for the shutdown on Democrats, a new poll suggests that majority of Americans hold him and the GOP responsible.  Vox notes that "according to [the recent] Washington Post-ABC News poll, more than half of Americans (53 percent) say the president and his party should shoulder most of the blame for the closures; another 29 percent point their finger at Democrats in Congress."
