U.S. Sen. Mary Landrieu says Republicans are intentionally drumming up fear about Ebola. GOP officials say the Democratic senator isn’t putting enough pressure on the Obama administration to address the public health concerns.

Landrieu said Tuesday that while Ebola is a very serious situation, Republicans are using the virus outbreak in West Africa to “create fear” here at home.

She didn’t respond directly to a question about President Barack Obama’s overall response. But she said she was pleased the Homeland Security Department is tightening airport screening for passengers from three West African countries with an Ebola outbreak.

Landrieu’s chief Republican opponent, Rep. Bill Cassidy, says Obama’s response has been ineffective and he’s called for a commercial travel ban between the U.S. and the countries with an outbreak of the virus.
