Announcer from nbc news World Headquarters in new york this is nbc nightly news. Reporting tonight, lester holt. Good evening. Facing a growing opposition from inside and outside the state, and a threat to its economy, indianas governor in an apparent response to glaring headlines like this in the Indianapolis Star has called for a change to the controversial law that some believe is worded in such a way it opens the door to legalized discrimination. While arguing that critics and some in the media have gotten it wrong, governor mike pence says he wants legislation on his desk this week that clearly spells out that the religious freedom law does not allow businesses to discriminate. As indiana calms the uproar tonight, another state may be ready to step into the fray with its own law. Gabe gutierrez has the story tonight. Reporter mike pence blasted his critics saying indianas new law is about religious freedom, not discrimination. This law has been smeared. Reporter the front page of the Indianapolis Star, fix this now. The governor said hes working with the lawmakers to clear the intent by the end of the week. Under this law, as its written, is it legal for a florist to deny services to a samesex couple citing their religious beliefs . This law does not give anyone a license to deny services to gay and lesbian couples. Reporter thats a different interpretation from eric miller one of the bills proponents who stood next to the governor during the bill signing. The bill would help christian bakers florists and photographers who should not be punished for refusing to participate in a homosexual marriage. Since then was i expecting this kind of backlash . Heavens no. Reporter nine ceos have sent a letter to state officials demanding the law be changed. The notion that you can tell businesses somehow that they are free to discriminate against people based on who they are is madness, its bad for business. Reporter indianapoliss republican mayor wants the law repealed unless repeal indianapolis will not be defined by this. Indianapolis welcomes everybody. Reporter other states now considering similar bills. Eight states please do not discriminate. Reporter late today the state house passed its own religious freedom bill. My bill is designed to protect peoples Civil Liberties when it comes to religion. Reporter now on its way to the governors desk. Tonight the debate also heating up in georgia and north carolina. So why did the law pass in indiana now . The governor says it was on the heels of the recent Hobby Lobby Supreme Court decision that strengthened religious protections. But critics of the bill say the timing was due to indianas samesex marriage ban being overturned last year. Gabe gutierrez, thank you. A Major Development tonight in the investigation into the crash of that germanwings plane in the mountains of france. The Parent Company lufthansa knew six years ago that the copilot who deliberately crashed the plane had suffered from severe depression. Nbcs bill neely has details. Reporter in a statement entitled lufthansa helps investigation process, the airline confirmed for the first time that Andreas Lubitz had a previous episode of devere depression. It says he wrote this in a 2009 email to the Flight Training pilot school so he could resume his training after dropping out for several months. Lufthansa said it has now given this email to prosecutors after further interm investigations. The key question is when did it know about the email. Once lubitz revealed his depression as a past issue, he resumed training and qualified as a pilot with lufthansa. The statement doesnt address how the airline followed up his past severe depression. Two days ago a lufthansa spokesman told nbc news the airline, quote, had no knowledge of medical problems during lubitzs employment. For days lufthansa and its subsidiary germanwings has tried to leave no room for doubt about its pilots and its procedures saying this two days after the crash. We have complete confident in our pilots. We have a Flight School which all our pilots have go through. Reporter lufthansas boss repeating the same 100 assurance about lubitz. 100 fit to fly without any restrictions, he says. Lufthansa faces a risk of multimillion dollar lawsuits of compensation over the crash. The fact that its officials were aware that lubitz had suffered from serious depression then later certified him to fly passenger jets will come under intense scrutiny. Tonight, french authorities are dismissing the claims of a french magazine and a german tabloid newspaper that a reporter has seen a cell phone video of the final seconds of the flight a video that somehow its claimed was recovered from the debris. A French Police spokesman tells nbc news tonight, this is false. It is a fake. Back to you, lester. Bill neely in france thank you. A manhunt in the virginia suburbs of washington, d. C.

Tom costello nbc news. Tonight after just two days of testimony, the defense has rested its case in the Boston Marathon bombing trial. The case will soon be in the hands of a jury. Pete williams reports, the final witnesses brought some surprises. Reporter the jury learned today that after the fbi scoured the scene for all the bits and pieces of the two Pressure Cooker bombs set off at the marathon 500 separate pieces in all, fingerprints were found on only two. A remnant of cardboard from the first bomb and a portion of the backpack that held the second. And all the fingerprints on those parts belonged to Dzhokhar Tsarnaevs older brother, tamer lin. And six other prints on it were tamerlans. Defense lawyers claim the major steps in preparing for the bomb attacks were taken by the older brother. But the government says its not surprising so few prints were found on bomb pieces and a former senior atf investigator agrees. Fingerprints are fragile. When a bomb detonates, heat flame and blast pressure can all destroy the fingerprints. Reporter a defense computer analyst said the al qaeda online magazine with bombmaking instructions were transferred from tamerlans computer to dzhokhars. The younger brother never went hunting for it online the expert said. On monday the lawyers give their closing arguments and the jury starts deliberating.
