We present the results of bi-monthly VLBA observations at 7mm in 1998-1999 of 15 radio-bright AGNs. These include 5 BL Lac objects (3C 66A, OJ 287, 1803+784, 1823+568, and BL Lac), 8 quasars (0420-014, 0528+134, 3C 273, 3C 279, PKS 1510-089, 3C 345, CTA 102, and 3C 454.3), and 2 radio galaxies (3C 111 and 3C 120). This is part of a mm-wave polarization monitoring program with the VLBA, JCMT, and (starting in February 1999) Steward Observatory, plus total flux density monitoring at BIMA and OVRO (mm array calibration data). Several of the sources (BL Lac, 3C 279, PKS 1510-089, and 3C 120) are being monitored weekly or semi-weekly with RXTE. The regular monitoring with high angular resolution allows us to identify components across different epochs with high confidence, and to determine with to high accuracy the extrapolated times of zero separation from the core. We will show the VLBA images and measurements of proper motions. For a number of sources the values of proper motions of components in the jets will be compared with the results of our previous program of VLBA monitoring of gamma -ray bright blazars at high frequencies in 1994--1997. This research is supported in part by the National Science Foundation through grant AST-9802941. The gamma -ray blazar VLBA monitoring was supported in part by various NASA guest investigator grants (RXTE and CGRO).
