Many Republicans criticized President Barack Obama for not cutting short his trip to Cuba in the aftermath of the Brussels terror attack. But a plurality of those Americans queried in one poll disagreed, although a similar number thought he should have skipped a ball game he attended while on the historic visit.  

More than 30 people were killed and hundreds were hurt in twin attacks on a subway station and the main airport on March 22. The Islamic State claimed responsibility. The coordinated strike in the heart of Europe renewed terror concerns in major U.S. cities as government buildings, transportation hubs and landmarks tightened security.

Brussels Attack: Are We Any Safer Here?
Lack of coordination between nations makes Europe vulnerable

As the smoke clears from another terrorist strike in the heart of Europe, U.S. lawmakers and security experts are warning violent extremists could similarly detonate bombs in an American airport or subway station.  

Take Dulles International Airport, about 25 miles west of Washington. It is not uncommon on a busy travel day to walk with large pieces of luggage -- big enough to carry deadly explosives capable of a Brussels-like strike -- from a daily parking garage to the ticketing area without encountering another person.

President Barack Obama characterized Tuesday's terror attacks in Brussels that killed more than 30 people “outrageous,” pledging to do whatever necessary to help Belgium.  

Speaking from Havana, Obama said the United States and other countries must "stand in solidarity" to combat "the scourge" of terrorism.

Capitol and Metro transit police were stepping up patrols Tuesday morning after coordinated terror attacks that killed at least 31 people in  Brussels, but officials said there was no evidence of increased threat to the Capitol.  

The Department of Homeland Security has not yet changed its national threat level but is closely monitoring the situation in Brussels and is in touch with counterparts in the region, said DHS spokeswoman Marsha Catron.
