By January 2011, El Khalifi was under federal surveillance.
[1][3] At a meeting in an Arlington residence he agreed when someone stated that the "war on terrorism" was a "war on Muslims," according to an informant.
[1][2][3] El Khalifi watched as the man produced an AK-47 rifle, two revolvers and ammunition, and discussed being ready to "fight back".

El Khalifi allegedly expressed a desire to be "associated with an armed extremist group."
[1] In December 2011, he was introduced to "Yusaf", an undercover officer. El Khalifi allegedly told Yusaf that he wanted to carry out a mass shooting at a
Washington DC restaurant frequented by military officers.
[1] He allegedly wanted to kill at least 30 people and was also considering targeting an office building in Alexandria, a restaurant, or a synagogue.
[5] He is said to have expressed interest in gunning people down "face-to-face."
[6]
On January 7, 2012, El Khalifi discussed a larger attack on a military facility.
[6] On January 15, El Khalifi changed his plan, allegedly telling under cover officers that he now wanted to carry out a suicide bombing.
[1] That same day he is said to have carried out a test with a cellphone detonation device.
[1] When the test was successful, he expressed a desire for larger explosives, enough to blow up a building.
[1][5] He selected February 17 as the day for his attack.
[6] He visited DC several times over the following weeks to plan his attack and purchased supplies, such as nails, for his operation.
[2][5] He asked for a gun to shoot anyone who tried to interfere with his "martyrdom operation" and request remote detonation of the bomb in the event he was captured.

On February 17, El Khalifi went to the
Dar Al-Hijrah Islamic Center to pray before embarking on a suicide mission.
[1] Authorities say he was "not a regular" at that
mosque or any other in the area.
[5] The mosque's
imam offered to provide authorities with surveillance footage, but was told it was not necessary.
[5] Later that day, El Khalifi was provided a disarmed suicide vest and
MAC-10 by Yusaf and transported to downtown Washington.
[1][6] He was arrested before he exited the parking building he had been dropped off in, as he walked alone toward the Capitol building.
[5] After the arrest, authorities raided his west
Alexandria residence and searched his property.
[6] "There is no doubt that this guy was committed," commented a law enforcement officer.
[1]
El Khalifi appeared in court that afternoon and was charged with attempting to use a weapon of mass destruction against US property.
[6] An attorney for the government stated "El Khalifi ... devised the plot, the targets and the methods on his own."
[6] A bail hearing was set for February 22.
[2] He was unemployed at the time of arrest and is not believed to have a genuine association with al-Qaeda.
[5] Authorities say they are close to arresting an associate of El Khalifi's on unrelated charges.
[5] "Today’s case underscores the continuing threat we face from homegrown violent extremists," remarked
Assistant Attorney General Lisa Monaco. "Thanks to a coordinated law enforcement effort, El Khalifi’s alleged plot was thwarted before anyone was harmed."
