I mean this is how he concluded his speech where he railed again and again about a “stolen election” and “taking the country back.” He fired them up with fury against politicians and sent them in the direction of Congress, 100%.
He planned this rally deliberately for Jan. 6 and D.C. when he can hold a rally anywhere and any time he wants
Rather than follow the crowd like he said he would, he went back to the WH and watched it all on TV for 6 hours before saying anything, even as aides were begging for attention. Ultimately Pence had to be the one to activate the National Guard
He has a shred of plausible deniability as he didn’t literally say “storm the Capitol” but you have to look at the full picture here
