George Takei reality-checked President Donald Trump’s congressional speech on Twitter.

As Trump addressed Congress for the first time as president on Tuesday, the “Star Trek” actor and activist went online to call him out on his claims.

For example, when Trump said America “stands united in condemning hate,” Takei retorted that wasn’t possible “when your AG is a racist, your VP attacks LGBTs, and your top advisor is a White Nationalist.”

You can't be "a country united against hate" when your AG is a racist, your VP attacks LGBTs, and your top advisor is a White Nationalist. — George Takei (@GeorgeTakei) March 1, 2017

Similarly, when Trump said he was going to make “communities safer for everyone,” Takei blasted him for “doing the NRA’s bidding and making it easier for mentally ill folks to buy guns.”

And on Trump’s claims that he would “drain the swamp,” Takei fired back that he couldn’t possibly be doing so “by appointing a billionaire dimwit as head of Education and an oilman CEO as head of state.”
