"US Senators Chris Murphy and Dianne Feinstein and US Representatives Judy Chu and Zoe Lofgren have each introduced companion bills in the US Senate and US House of Representatives to block the implementation of President Trump’s executive order blocking travel from majority Muslim countries," the release said. "The bills, S. 246and H.R. 810, would prohibit the use of any funds or fees to implement Executive Order 13780, signed on March 6, 2017."
On January 27, 2017, one week after taking office, Trump first introduced a ban prohibiting entry of foreign nationals from seven Muslim majority countries although court challenges forced the administration to modify the ban multiple times.
The Supreme Court in June upheld the current version of the executive order, also referred to as travel ban 3.0, which bars travelers from seven countries including five Muslim majority nations — Iran, Libya, Somalia, Syria, and Yemen — in addition to North Korea and Venezuela.
